A review of bimetallic osmium–tin and osmium–germanium carbonyl complexes

Over the past few years, there have been several reports on bimetallic di–, tri–, tetra–, and polynuclear osmium–tin and osmium–germanium carbonyl complexes. This review describes recent studies on the synthesis and characterization of these carbonyl complexes of varying nuclearity and some of their reactivities. Albeit, the studies of their applications have barely been reported or virtually ignored, the salient features on their formation, structure and bonding are described.

Thermolysis of [HOs3(CO)8{µ3-Ph2PCH2P(Ph)C6H4}]: New Os2- and Os3- cluster products based on multiple C[sbnd]H bond activation of the bis(diphenylphosphino)methane ligand

Thermolysis of [HOs3(CO)8{µ3-Ph2PCH2P(Ph)C6H4}] in refluxing xylene has been investigated, and three new polynuclear osmium compounds containing an activated dppm ligand(s) as a result of multiple CH bond cleavages have been isolated. The new complexes are [H2Os3(CO)8{µ3-Ph2PCHP(Ph)C6H4}] (1), [H2Os3(CO)6(µ3-Ph2PCHPPh2){µ3-Ph2PCH2P(Ph)C6H4}] (2) and [Os2(CO)6{µ-H4C6(Ph)PCH2P(Ph)C6H4}] (3), each of which exhibits a different coordination mode involving the activated diphosphine ligand. Cluster 1 is formed by CH bond oxidative addition of the backbone methylene spacer and an ortho site at an ancillary aryl ring. Control experiments confirm that cluster 2 is formed from cluster 1 and dppm. The dinuclear compound 3 is formed via metalation of two phenyl rings on the dppm ligand and is accompanied by the release of an osmium atom. The molecular structure of each new complex has been established by single-crystal X-ray diffraction analysis, and the bonding in compounds 1–3 has been examined by DFT calculations.

Facile Os-Os bond cleavage in the reactions of [Os3(CO)10(NCMe)2] and [Os3(CO)10(μ-H)2] with tetramethylthiuram disulfide (tmtd): Syntheses and crystal structures of new polynuclear osmium carbonyl complexes containing a dimethyldithiocarbamate ligand(s)

The reaction of the labile triosmium cluster [Os3(CO)10(NCMe)2] with tetramethylthiuram disulfide [(Me2NCS2)2, tmtd] has been investigated at room temperature. Conducting the reaction under mild conditions has permitted the isolation of the three new polynuclear osmium complexes [Os3(CO)10{κ2(S,S)-S2CNMe2}2] (1), [Os4(CO)12{κ2(S,S)-S2CNMe2}2{μ3-η1(C),κ2(O,O)-CO2)}(μ3-S)] (2) and [Os3(CO)9{μ3-η1(C),κ1(S)-SCNMe2}{μ-κ1(S)-SC(O)NMe2}] (3) in 20, 16 and 10% yield, respectively, in addition to the known mononuclear complex [Os(CO)2{κ2(S,S)-S2CNMe2}2] (4) in 10% yield. The triosmium complex 1 has a linear arrangement of osmium atoms with each terminal osmium center containing a chelating Me2NCS2 ligand. The tetraosmium complex 2 also possesses a μ3-CO2 ligand in addition to capping sulfido and chelating Me2NCS2 ligands. Complex 3 contains an open triosmium core with the open Os···Os edge bridged by a Me2NC(O)S ligand and a capping Me2NCS ligand. A similar reaction between the unsaturated cluster [Os3(CO)10(μ-H)2] and [(Me2NCS2)2] yielded the triosmium complexes [Os3(CO)10{μ-κ1(S)-S2CNMe2}(μ-H)] (5) and [Os3(CO)9{μ3-κ2(S,S)-S2CNMe2}(μ-H)] (6) in addition to compounds 1 and 4 and the known hydroxyl cluster [Os3(CO)10(μ-OH)(μ-H)] (7) in 7, 14, 14, 10, and 6% yield, respectively. Both 5 and 6 possess a triosmium core, and the Me2NCS2 ligand acts in edge-bridging capacity in the former while it serves as a face-capping ligand in the latter. All new complexes have been characterized by combustion analyses and IR and NMR spectroscopies, and the solid-state structures of 1–3, and 6 have been established by X-ray crystallography. The bonding in clusters 1-3 and 6 has been examined by electronic structure calculations, and the thermodynamics for the formation of 1 and MeCN (two equiv) from [Os3(CO)10(MeCN)2] and tmtd, relative to other chelated and bridged isomers of [Os3(CO)10(tmtd)] are discussed.

Activation of thiosaccharin at a polynuclear osmium cluster

The reaction of thiosaccharin (tsacH) with the triosmium cluster [Os3(CO)10(NCMe)2] furnishes the decacarbonyl isomers [HOs3(CO)10(μ-S-tsac)] (1) and [HOs3(CO)10(μ-N,S-1,3-tsac)] (2) in a 3:1 ratio at room temperature. These isomers differ by the coordination mode displayed by tsac ligand. The tsac moiety functions as an edge-bridging ligand via the sulfur atom in 1 while in 2 the bridging of adjacent osmium centers is achieved through the sulfur and nitrogen groups. The ancillary hydride in both products shares the OsOs edge that is bridged by the heterocyclic ligand. Heating 1 at 80 °C affords 2 and demonstrates that the former cluster is the product of kinetic control. The conversion of 1 → 2 has been investigated by DFT and the isomerization pathway elucidated. The DFT calculations confirm cluster 2 as the thermodynamically preferred isomer in this pair of products. Thermolysis of 2 in refluxing toluene affords the hexanuclear cluster [H2Os6(CO)17(μ-C,N-1,2-C6H4CNSO2)2(μ3-S)(μ4-S)] (3) via carbon-sulfur bond scission and subsequent capture of the extruded sulfur by the cluster core. The molecular structures for the three new clusters have been determined by single-crystal X-ray diffraction analyses.

Phenazine-substituted polynuclear osmium clusters: Synthesis and DFT evaluation of the C-metalated derivatives Os3(CO)9(μ3,η2-C12H7N2)(μ-H) and Os3(CO)9(μ3,η2-C12H6N2)(μ-H)2

Os3(CO)12 reacts with phenazine in refluxing xylene to yield the monohydride cluster Os3(CO)9(μ3,η2-C12H7N2)(μ-H) (1) in 18% yield and the dihydride cluster Os3(CO)9(μ3,η2-C12H6N2)(μ-H)2 (2) in 21% yield. Compound 1 reacts reversibly with CO to give the decacarbonyl compound Os3(CO)10(μ,η2-C12H7N2)(μ-H) (3) and with PPh3 to afford the addition product Os3(CO)9(μ,η2-C12H7N2)(PPh3)(μ-H) (4). Compounds 1, 2, and 4 have been structurally characterized. 1 contains a C-metalated phenazine ligand that is coordinated to the cluster by a dative nitrogen bond and a benzylidene-type bond, the latter which bridges the same cluster edge as the bridging hydride. The activated phenazine ligand in 2 derives from a double C–H bond metalation sequence, affording a face-capping heterocyclic ligand that binds adjacent osmium centers through two σ–Os–C bonds and the third osmium atom via an aryl π bond in an η2 fashion. Compound 4 exhibits a closed trimetallic Os3(CO)9 core that contains edge-bridging phenazine (C,N coordination) and hydride moieties, and a triphenylphosphine ligand that is coordinated at the non-phenazine-ligated osmium center. These compounds represent rare examples of polynuclear osmium clusters containing C-metalated phenazine ligands. The potential energy surfaces that afford clusters 1 and 2 from Os3(CO)12 and phenazine have been modeled by DFT calculations, and these data indicate that both product clusters originate from the unsaturated cluster Os3(CO)11.

Polynuclear osmium–dioxolene complexes: comparison of electrochemical and spectroelectrochemical properties with those of their ruthenium analogues

Reaction of [Os(bipy)2Cl2] (bipy = 2,2′-bipyridine) with the poly-dioxolene ligands 3,4,3′,4′-tetrahydroxybiphenyl (H4L1), 2,3,6,7-trihydroxy-9-phenylxanthen-3-one (H3L2) or 2,3,6,7,10,11-hexahydroxytriphenylene (H6L3) afforded the complexes [{Os(bipy)2}2(μ-L1)][PF6]2, [{Os(bipy)2}2(μ-L2)][PF6]3, and the trinuclear complex [{Os(bipy)2}3(μ-L3)][PF6]3 abbreviated as [Os2(L1)]2+, [Os2(L2)]3+ and [Os2(L3)]3+, respectively. In these complexes two or three {OsIII(bipy)2(OO)} fragments are linked by the conjugated bridging ligands (where OO denotes a dioxolene binding site in any oxidation state). The complexes exhibit rich electrochemical behaviour, displaying a combination of metal-centred OsIII–OsII couples (as reductions) and ligand-centred couples (as oxidations). UV/VIS/NIR spectroelectrochemical analysis was carried out on all three complexes in all accessible oxidation states, and the spectra were assigned with reference to the mononuclear model complex [OsIII(bipy)2(cat)][PF6] (H2cat = catechol) which was also examined spectroelectrochemically, as well as being crystallographically characterised. The comparison with the previously described ruthenium analogues is interesting due to their different internal oxidation state distribution. Whereas the mononuclear complex [OsIII(bipy)2(cat)]+ contains OsIII co-ordinated to a catecholate (oxidised metal, reduced ligand), the ruthenium analogue in the same oxidation state is [RuII(bipy)2(sq)]+ (sq = 1,2-benzosemiquinone monoanion), i.e. reduced metal and oxidised ligand. The same pattern of behaviour persists in the dinuclear and trinuclear complexes, and leads to interesting differences in the electrochemical properties of the ruthenium and osmium congeners.

Structural studies on polynuclear osmium carbonyl hydrides. XXXVI. The crystal structure of (μ-H)2Os3(CO)9(μ3-η1-CCO), a case wherein internally inconsistent OsOs bond lengths can be explained by the presence of both ordered and disordered molecular sites in the crystal

Abstract The complex (μ-H) 2 Os 3 (CO) 9 (μ 3 -η 1 -CCO) crystallizes in the monoclinic space group P 2 1 / m (No. 11) with a 9.2721(15), b 14.2272(21), c 12.6005(19) A, β 92.423(13) o , V 1660.7(4) A 3 and Z = 4. Diffraction data (Mo- K α , 2θ = 4.0–45.0 o ) were collected on a Syntex P 2 1 /XTL system and the structure refined to R 6.5% for all 2292 reflections ( R 4.9% for those 1805 data with | F o | > 3σ (| F o |)). Molecules are bisected by crystallographic mirror planes; the asymmetric unit therefore consists of two independent half molecules. Site “A” contains ordered molecules (OsOs 2.760(1) A, 2 × Os(H)Os 2.870(1) A) but site “B” is associated with anomalous OsOs distances (2 at 2.813(1) A, 1 at 2.875(1) A) which can be explained successfully by a two-fold pattern of disorder; other anomalies in inter-atomic parameters at site B are consistent with this explanation.

Structural studies on polynuclear osmium carbonyl hydrides: XXXIV. Elucidation of the molecular structure from a crystal structure of disordered (μ-H) 5Os 3Re(CO) 12

The complex (μ-H) 5Os 3Re(CO) 12 crystallizes in the centrosymmetric hexagonal space group P6 3/ m ( C 2 6 h ; No. 176) with a 19.087(5), c 10.963(1) Å, V 3459(3) Å 3, and Z = 6. Diffraction data were collected on a Syntex P2 1 automated four-circle diffractometer (Mo- K α radiation, 2θ = 4.5–45.0°) and the structure was refined to R F = 7.9% for all 1480 unique reflections ( R F = 5.4% for those 1007 data with ¦ F o¦ > 6σ(¦ F o¦)). The molecule contains a tetrahedral core of metal atoms each associated with three terminal carbonyl ligands. It is bisected by a crystallographic mirror plane. Although the hydride ligands were not located, a consideration of metal-metal distances allows the distinction between osmium and rhenium atoms and suggests that the structure is subject to a subtle form of two-fold disorder.
