Synthesis and characterization of group 6-9 metal-rich homo- and hetero-metallaboranes

To isolate the metal-rich metallaboranes of group 6-9, we have performed the reaction of various reaction intermediates, generally synthesized from the low-temperature reactions of [Cp∗WCl4] (Cp∗ ​= ​η5-C5Me5), [(Cp∗RhCl2)2], or [(Cp∗RuCl2)2] and [LiBH4 THF] with different transition metal carbonyl compounds. For example, the thermolytic reaction of [Fe2(CO)9] with an in situ generated intermediate, produced from the reaction of [Cp∗WCl4] and [LiBH4THF] afforded a trigonal bipyramidal cluster, [(μ3-BH)2H2{Cp∗W(CO)2}{Cp∗W(CO)}{Fe(CO)3}], 1 which contains a triply-bridging bis-{hydrido(borylene)} ligand. Similarly, the reaction of [Co2(CO)8] with nido-[(RhCp∗)2(B3H7)] I at room temperature, yielded an octahedral cluster, [(Cp∗Rh)2B2H2Co2(CO)5(μ3-CO)], 2. In this reaction, nido-I having (n+2) skeletal electron pairs (SEP) goes on for the formation of a closo-rhodaborane with (n+1) SEP. In addition, we have isolated a trinuclear bis(μ3-oxo) metalla cluster [(Cp∗Ru)3(μ3-OBF3)2(μ-H)], 3. Compound 3 can be considered as cluster having trigonal bipyramidal geometry with exo-BF3 fragment. All these clusters were characterized by IR, mass spectrometry, NMR, and single-crystal X-ray crystallographic analysis.

The interplay between spin densities and magnetic superexchange interactions: case studies of mono- and trinuclear bis(oxamato)-type complexes.

For future molecular spintronic applications the possibility to modify and tailor the magnetic properties of transition-metal complexes is very promising. One of such possibilities is given by the countless derivatization offered by carbon chemistry. They allow for altering chemical structures and, in doing so, to tune magnetic properties of molecular spin-carrying compounds. With emphasis on the interplay of the spin density distribution of mononuclear and magnetic superexchange couplings of trinuclear bis(oxamato)-type complexes we review on efforts on such magneto-structural correlations.

Optical and magneto-optical properties of spin coated films of novel trinuclear bis(oxamato) and bis(oxamidato) type complexes

This work reports the first example of the spectroscopic measurements of the Magneto-Optical Kerr Effect (MOKE) of films being composed of trinuclear transition metal complexes on a non-transparent substrate at room temperature. The thin films of the tailor-made trinuclear bis(oxamidato) type complex 5 ([Cu3(opbonPr2)(tmcd)2(NO3)2], opbonPr2 = o-phenylenebis(N’-npropyloxamido, tmcd=trans-(1R,2R)-N,N,N′,N′-tetramethyl-cyclohexanediamine) and of the bis(oxamato) type complexes 11 ([Cu2Ni(opbaCF3)(pmdta)2(NO3)2], opbaCF3 = 4-trifluoromethyl-o-phenylenebis(oxamato), pmdta = N,N,N,′N″,N″-pentamethyldiethylenetriamine) and 12 ([Cu3(opba)(bppe)2(NO3)2] (opba = o-phenylenebis(oxamato), bppe = S-N,N-bis(2-picolyl)−1-phenylethylamine) were fabricated by spin-coating and their thicknesses in the range between 0.5µm and 2µm was determined by spectroscopic ellipsometry. Based on the spectroscopic ellipsometry results it was also possible to determine the optical constants of the film and compare them with the absorption of the complexes in solution in order to confirm the complex integrity after the film deposition. The fabrication of high-quality films which exhibit Kerr rotation up to 0.2mrad (11.5mdeg) was only possible due to tailor-made synthesis, which allows circumventing intermolecular interactions of the trinuclear complexes during the film formation.

Reactivity of an All‐Ferrous Iron–Nitrogen Heterocubane under Reductive and Oxidative Conditions

The reactivity of the all-ferrous FeN heterocubane [Fe4 (Ntrop)4 ] (1) with i) Brønsted acids, ii) σ-donors, iii) σ-donors/π-acceptors, and iv) one-electron oxidants has been investigated (trop = 5H-dibenzo[a,d]cyclo-hepten-5-yl). 1 showed self-re-assembling after reactions with i) and proved surprisingly inert in reactions with ii) and iii), with the exception of CO. Reductive and oxidative cluster degradation was observed in reactions with CO and TEMPO, respectively. These reactions yielded new cluster compounds, namely a trinuclear bis(μ3 -imido) 48 electron complex in the former case and a tetranuclear all ferric μ-oxo-μ-imido species in the latter case. Characterization techniques include NMR and in situ IR spectroscopy, single crystal X-ray analysis, Mössbauer spectroscopy, cyclic voltammetry, magnetic susceptibility measurements, and DFT calculations.

Spectroscopic characterization of N,N'-bis(salicylidene)pentane-1,3-diamine nickel(II) complex

The <TEX>$N_2O_2$</TEX> tetradentate Schiff base ligand, N,N'-bis(salicylidene)pentane-1,3-diamine (Salpn), coupled with 1:2 concentration ratio of 1,3-diaminopentane and salicylaldehyde was used to produce a series of macrocyclic Nikel(II) complexes. In the metal complexation, it was observed that Salpn macrocyclic ligand can adopt more than a metal ion giving an unique multinuclear metal complexes including Ni(II)Salpn and <TEX>$Ni(II)_3(Salpn)_2$</TEX>. Characteristic IR <TEX>${\upsilon}(M-O)$</TEX> peaks for Ni(II)Salpn and <TEX>$Ni(II)_3(Salpn)_2$</TEX> were observed to be <TEX>$1028cm^{-1}$</TEX> and <TEX>$1024cm^{-1}$</TEX>, respectively. Characteristic UV-Vis absorption <TEX>${\lambda}_{max}$</TEX> peaks for <TEX>$Ni(II)_3(Salpn)_2$</TEX> were observed to be 241nm and 401 nm. Structural characterization of <TEX>$Ni(II)_3(Salpn)_2$</TEX> by NMR exhibits that the salicylidene ring moiety has two different resonance signals originated from the magnetically asymmetric diligand and trinuclear bis complex. Complete NMR signal assignments and characterizations elucidating structural features of <TEX>$Ni(II)_3(Salpn)_2$</TEX> were described in detail.

A Novel Al-Bridged Trinuclear Iron(II) Bis(imino)pyridyl Complex with Catalytic Ethylene Polymerization Behavior

A self-assembled Al-bridged diiminopyridine-based ligand (3) was synthesized and characterized by FT-IR, ESI-MS and NMR spectroscopy. Electron spectral titrations were performed to confirm the formation of a novel trinuclear bis(imino)pyridyl iron(II) complex (4) upon addition of <TEX>$FeCl_2$</TEX> into Al-bridged ligand 3 in methanol solution. Simultaneously, a typical bis(imino)pyridine-iron(II) complex (2) was synthesized and fully characterized. The X-ray crystal study of the iron(II) complex 2 disclosed a five-coordinate, distorted square-pyramidal structure with the tridentate N^N^N ligand and chlorides. The optimal molecular structure of 4 was obtained by means of molecular mechanics, which showed that each iron atom in the complex 4 is surrounded by two chlorides, a tridentate N^N^N ligand and one oxygen atom, supporting considerations about the possibility of six-coordinate geometry from MMAO or the ethylene access. A comparison of 4 with the reference 2 revealed a remarkable decrease of the catalytic activity and MMAO consumption (activity up to <TEX>$0.41{\times}10^3\;kg\;{mol_{Fe}}^{-1}h^{-1}bar^{-1}$</TEX>, Al/Fe = 650 for 4 and <TEX>$7.02{\times}10^3\;kg\;{mol_{Fe}}^{-1}h^{-1}bar^{-1}$</TEX>, Al/Fe = 1600 for 2).

Pincer Chromium(II) and Chromium(III) Complexes Supported by Bis(imino)aryl NCN ligands: Synthesis and Catalysis on Isoprene Polymerization

Reactions of 2,6-(ArN═CH)2C6H3Li with CrCl2(THF)2 afford two trinuclear bis(imino)aryl NCN pincer Cr(II) complexes {[2,6-(ArN═CH)2C6H3]Cr(μ-Cl)2}2Cr [Ar = 2,6-Me2C6H3 (1a), 2,6-Et2C6H3 (1b)], and a mononuclear bis(imino)aryl NCN pincer Cr(II) complex [2,6-(ArN═CH)2C6H3]Cr(μ-Cl)2Li(THF)2 [Ar = 2,6-iPr2C6H3 (1c)], respectively. Similar reactions of 2,6-(ArN═CH)2C6H3Li with CrCl3(THF)3 produce only mononuclear bis(imino)aryl NCN pincer Cr(III) complexes [2,6-(ArN═CH)2C6H3]CrCl2(THF) [Ar = 2,6-Me2C6H3 (2a), 2,6-Et2C6H3 (2b), 2,6-iPr2C6H3 (2c)]. X-ray crystallographic analysis reveals that the terminal Cr(II) atoms in 1a and 1b and the Cr(II) atom in 1c possess a distorted trigonal bipyramidal coordination environment with the Cipso atom of the pincer ligand and two chloride atoms in the equator and the two imine nitrogen atoms in the apical positions, while the Cr(III) complexes 2a, 2b, and 2c all adopt a distorted octahedral geometry around the chromium metal. Upon activation with trialkylaluminum and [Ph3C]+[B(C6F5)4]−, the Cr(III) complexes show high catalytic activity for isoprene polymerization and afford polyisoprene with predominately trans-1,4 units, whereas the Cr(II) complexes are inert under the same conditions.

Halogermanium(II) Complexes Having Phenylamidinate As Supporting Ligands: Syntheses, Characterizations, and Reactivities

Novel germylenes [{Me3SiNC(Ph)NSiMe3}GeX] (X = Cl, Br, I) and [{Me3SiNC(Ph)NSiMe3}2Ge] with the bidentate phenylamidinato ligand have been synthesized in high yields by a salt metathesis reaction between Cl2Ge·dioxane or I2Ge and the lithium salt of the ligand. They were characterized by 1H and 13C NMR and mass spectrometry and single-crystal X-ray structure analyses, which confirmed N-chelation and a three-coordinate germanium center. The cycloaddition reactions with o-quinone led to cycloadducts, whose structures were determined by X-ray analyses. The chelation of the ligand to the metal center was conserved, affording penta- and hexacoordinated germanium(IV) atoms. Complexation reactions with [codW(CO)4] and [nbdMo(CO)4] resulted in trinuclear bis(germanium(II)) transition-metal complexes in “trans” octahedral geometry.

Synthesis, characterization and magnetic properties of new homotrinuclear copper(II) complexes

Two new mononuclear bis(oxamato) complexes with the formula [ nBu 4N] 2[M(nabo)] M = Ni ( 4), Cu ( 5), with nabo = 2,3-naphthalene-bis(oxamato) have been synthesized as precursors for trinuclear oxamato-bridged transition metal complexes. Starting from 5 the homo-trinuclear complex [Cu 3(nabo)(pmdta) 2(BF 4)](BF 4) · MeCN · Et 2O ( 7), with pmdta = N, N, N′, N″, N″-pentamethyldiethylenetriamine, has been prepared. The central N, N′-2,3-naphthalene bridge of 7 is so far the most extended π-conjugated bridge of trinuclear bis(oxamato) type transition metal complexes. The goal of this work was to verify the N, N′-2,3-naphthalene bridge of 7 on its magnetic properties in comparison to the N, N′- o-phenylene bridge of the related homo-trinuclear complex [Cu 3(opba)(pmdta) 2(NO 3)](NO 3) · 2MeCN ( 6) (opba = o-phenylene-bis(oxamato)). The crystal structures of 4– 7 were solved. The magnetic properties of 6 and 7 were studied by susceptibility measurements versus temperature. For the intramolecular J parameter, values of −89 cm −1 ( 6) and −113 cm −1 ( 7) were obtained. The different J values are discussed based on the crystal structures of 6 and 7.

Ferrocenyl-functionalised terpyridines and their transition-metal complexes: syntheses, structures and spectroscopic and electrochemical properties.

Terpyridine ligands of the type Fc'-X-tpy (Fc'=ferrocenyl or octamethylferrocenyl, X=rigid spacer, tpy'=4'-substituted 2,2':6',2''-terpyridine) were prepared, crystallographically characterised and used for the synthesis of di- and trinuclear bis(terpyridine) complexes of RuII, FeII and ZnII. Donor-sensitiser dyads and triads based on RuII were thoroughly investigated by (spectro)electrochemistry, UV/Vis, transient absorption and luminescence spectroscopy, and an energy level scheme was derived on the basis of the data collected. Intramolecular quenching of the photoexcited RuII complexes by the redox-active Fc' groups can occur reductively and by energy transfer. Both the redox potential of the donor Fc' and the nature of the spacer X have a decisive influence on excited-state lifetimes and emission properties of the complexes. Some of the compounds show room-temperature luminescence, which is unprecedented for ferrocenyl-functionalised compounds of this kind.

A trinuclear bis(dioximate)(chloro)(nitrosyl)ruthenium(II) complex containing two (2,2′-bipyridine)copper(II) groups

A trinuclear bis(cyclohexanedioximate)(chloro)(nitrosyl)ruthenium(II) complex containing two (2,2′-bipyridine)-copper(II) groups has been synthesized and its electronic and electrochemical properties investigated. According to ZINDO/S calculations, the electronic structure of the ruthenium(dioximate)(nitrosyl) moiety is strongly delocalized. The electrochemical behavior has been interpreted with the aid of spectroelectrochemical measurements. In the trinuclear complex, it has been shown that the copper(II) ions can promote the oxidation of the NO species generated electrochemically, and also mediate the redox reactions of the complex, under a dioxygen atmosphere.

Synthesis of Bi- and Trinuclear Bis(alkynyl) Complexes [PtM (M = Rh, Ir), PtRh2] Starting from [cis-Pt(C6F5)2(C⋮CR)2]2-

The course of the reactions of Q2[cis-Pt(C6F5)2(C⋮CR)2] (Q = PPh3Me, R = Ph 1a; Q = NBu4, R = tBu 1b, SiMe3 1c) with [M(μ-Cl)(COD)]2 (M = Rh, Ir) is strongly influenced by the metal and the substituents, as well as the stoichiometry. Thus, whereas treatment of 1a with either 0.5 or 1 equiv of [Rh(μ-Cl)(COD)]2 gives the chelating-type binuclear highly polar compound (PPh3Me)[cis-Pt(C6F5)2(μ-1κCα:η2-C⋮CPh)2Rh(COD)], 2a, analogous reactions using 1b as the precursor afford only the trinuclear complex (NBu4)[{cis-Pt(C6F5)2(μ-1κCα:η2-C⋮CtBu)2}{Rh2(μ-Cl)(COD)2}], 4b. On the other hand, related bi- and trinuclear SiMe3 derivatives (NBu4)[cis-Pt(C6F5)2(μ-1κCα:η2-C⋮CSiMe3)2Rh(COD)], 2c, and (NBu4)[{cis-Pt(C6F5)2(μ-1κCα:η2-C⋮CSiMe3)2}{Rh2(μ-Cl)(COD)2}], 4c, are easily obtained by treating 1c with the binuclear rhodium substrate in the adequate molar ratio [1:0.5 for 2c; 1:1 for 4c]. Complex 2b and, alternatively, 2a,c derivatives can be produced by reacting 1 with the cationic solvento species [Rh(COD)(Et2O)x]+ (prepared in situ). The molecular structures of 2a and 4b have been confirmed by X-ray diffraction. By contrast, whereas the reactions of 1a,b with [Ir(μ-Cl)(COD)]2 lead to the formation of undefined products, the heterobinuclear σ,π double-alkynyl-bridged complex (NBu4)[cis-Pt(C6F5)2(μ-1κCα:η2-C⋮CSiMe3)(μ-η2:2κCα-C⋮CSiMe3)Ir(COD)], 3c, (X-ray) is isolated from reaction of 1c with the dimer iridium complex regardless of the molar ratio used (1:0.5 or 1:1).

Inter- and Intramolecular Hydrogen-Bonding Interaction of Hydroxo Groups and Steric Effect of Alkyl Substituents on Pyrazolyl Rings in TpR Ligands: Synthesis and Structural Characterization of Chloro-, Acetylacetonato-, and Hydroxo Complexes of VO2+ with TpPri2 and TpMe2 Ligands

Novel vanadyl (VO2+) chloro and hydroxo complexes with the hindered TpPri2 (hydrotris(3,5-diisopropyl-1-pyrazolyl)borate) and TpMe2 (hydrotris(3,5-dimethylpyrazolyl-1-pyrazolyl)borate) ligands were prepared and structurally characterized successfully. Ligand displacement of VOCl2(MeCN)2(H2O) by TpR afforded a series of octahedral chloro complexes, TpRV(O)(Cl)(X) (1: R = Pri2, X = PzPri2H; 2: R = Pri2, X = py; 6: R = Me2, X = NCMe). Hydrolysis of the obtained chloro complexes yielded the corresponding hydroxo complexes 4, 5, and 7, but their structures were very unique and different from that of the previously reported dinuclear VO2+ bis(μ-hydroxo) complex with the less hindered TpH2 (hydrotris(1-pyrazolyl)borate) ligand. For the TpPri2 complexes, the octahedral hydroxo−aqua complex, TpPri2V(O)(OH)(OH2) (4), and the trinuclear bis(μ-hydroxo)bis(μ-pyrazolato) complex, TpPri2V(O)(μ-OH)(μ-PzPri2)V(O)(μ-OH)(μ-PzPri2)V(O)TpPri2 (5), were isolated. The hydroxo−aqua complex 4 was dimerized through the intermol...

Diffusional and Internal Rotation in Single and Linked Trinuclear Bis(carbyne) Cluster Complexes Determined by (13)C NMR Relaxation Time Measurements.

Carbon-13 NMR relaxation times have been measured as a function of temperature for a family of bis(carbyne) cluster complexes: (CpCo)(3)(&mgr;(3)-CPh)(2) (1a), (CpCo)(3)(&mgr;(3)-CH)(&mgr;(3)-CPh) (1b), and X(1,4-C(6)H(4))Y with X = Y = (CpCo)(3)(&mgr;(3)-CPh)(&mgr;(3)-C-) (2); X = (CpCo)(3)(&mgr;(3)-CPh)(&mgr;(3)-C-), Y = -C&tbd1;CPh (3); or X = Y = -C&tbd1;CPh (4). These molecules can be regarded as symmetric top molecules in which the phenyl rings are adjacent to zero, one, or two Cp(3)Co(3) metal cluster units. Molecular rotational diffusion coefficients about the different axes of the molecules (D( perpendicular)and D(s)) obtained from the relaxation times indicate that the motions of the molecules are highly anisotropic. Rapid internal rotation of the phenyl rings described by the rotation rates R contributes significantly to that anisotropy. Phenyl rings adjacent to an alkyne group rotate at a rate comparable to that of free benzene whereas phenyl rings bound to a (CpCo)(3) group through a &mgr;(3)-carbyne ligand show significantly reduced rates of rotation. The observed difference in rotation rates is believed to be due primarily to steric interactions between phenyl rings and their substituents.

Mono-, bi- and trinuclear bis(allyl) complexes of ruthenium(IV) containing N-donor ligands

The ruthenium(IV) bis(allyl) complex [{Ru(μ 3 : μ 3-C 10H 16)Cl(μ-Cl)} 2] ( 1) reacts with pyrazene to give a binuclear complex, [{Ru(μ 3 : μ 3-C 10H 16)Cl 2} 2(μ-N 2C 4H 4)] ( 2), which exists in two diastereomeric forms of C i ( meso) and C 2 ( rac) symmetries. The analogous reaction with 1,3,5-triazine yields a mixture of mono-, bi- and trinuclear complexes, [{Ru(μ 3 : μ 3-C 10H 16)Cl 2} n (N 3C 3H 3 [ n = 1 ( 4), n = 2 ( 5), n = 3 (6), which interconvert with one another in chloroform solution at room temperature. Complexes 5 and 6 have been isolated and, like 2, 5 exists as two diastereoisomers. Complex 6, however, possesses four isomeric forms. The class I mixed-valence Ru IV-Ru II pyrazene-bridged complex [(Ru(μ 3 : μ 3-C 10H 16)Cl 2(μ-N 2C 4H 4)RuCl 2(μ 6- p-MeC 6H 4CHMe 2)] 7b) is also reported. Pretreatment of 1 with Ag[BF 4] in acetone generates mono- and dicationic solvate species which readily react with polypyridyl and related ligands to generate the chelate species [Ru(μ 3 : μ 3-C 10H 16)Cl(L-L)[BF 4] [L-L = 2,2′-bipyridyl ( 11), L-L = 1,10-phenanthroline ( 12)] and [Ru(μ 3 : μ 3-C 10H 16)(terpy)][BF 4] 2 ( 13) (terpy = 2,2t' : 6′,2″-terpyridine). Complex 11 has been characterized by X-ray crystallography.

Mono-, bi- and trinuclear bis(diphenylarsino)methane gold complexes. Crystal and molecular structure of [{(C 6F 5) 3Au(Ph 2AsCH 2AsPh 2)} 2Ag(OClO 3)]dd]Dedicated to Professor Rafael Usón on his 60th birthday.

Addition of bis(diphenylarsino)methane (dpam) to neutral or cationic gold(l) or gold(III) complexes containing weakly coordinating ligands leads to the formation of mononuclear {R 3Au(dpam), R 2ClAu(dpam), [R 2Au(dpam)]ClO 4 (RC 6F 5)} or binuclear complexes {RAu(dpam)AuR, [Au 2(dpam) 2](ClO 4) 2}. Mixed gold(III)gold(I) compounds can be synthesized either by oxidation of the gold(I) complexes or from mononuclear gold(III) derivatives. Reaction of R 3Au(dpam)with ClAu(tht), [Au(tht) 2]ClO 4 or AgClO 4 leads to the trinuclear complexes [{R 3Au(dpam)} 2Au]X (X=[AuCl 2] or ClO 4) or [{R 3Au(dpam)} 2Ag(OClO 3)], respectively. The structure of the silver complex has been determined by X-ray crystallography.

Synthesis and characterization of new di- and tri-nuclear cyano-bridged bis(dioximato)cobalt(III) complexes

Several new neutral and cationic di- and tri-nuclear cyano-bridged bis(dioximato)cobalt(III) complexes have been synthesized and characterized (dioximato = dimethylglyoximato or diphenylglyoximato). These compounds are obtained through substitution of labile axial ligands by the nitrogen of the cyano-group in [Co(dioximato)2(CN)2]− or [LCo(dioximato)2(CN)] (L = H2O, NH3, or py). In the first case, the existence of only one band in the CN-stretching region of the i.r. spectrum at 2190–2200 cm−1 is indicative of a trinuclear compound, while the presence of a second band at 2140 cm−1 attributable to a terminal cyano-group indicates a dinuclear structure. In the presence of water, aquation of axial positions may take place at the same time as bridge formation, whereas the use of a non-aqueous solvent allows the preparation of complexes with pyridine or NH3.

A linear trinuclear macrocyclic copper(II) complex

Reaction of the funcationalised macrocycle (1a) with copper (II) ions in solution leads to the assembly of a trinuclear bis(macrocyclic) complex which has been studied by X-ray crystallography and cyclic voltammetry; the complex contains a linear trinuclear array of copper atoms in which the central copper is in a square-planer environment.
