Syntheses, structures, corresponding fluorescence and magnetism of Zn(II) and Mn(II) coordination complexes based on 1-(3,5-dicarboxylatobenzyl)-1,2,4-1-H-triazole-3-carboxylic acid

Two new coordination complexes [Zn2(HL)2(phen)2]·4H2O (1) and [Mn(HL)(H2O)2]n (2) (H3L = 1-(3,5-dicarboxylatobenzyl)-1,2,4-1-H-triazole-3-carboxylic acid, phen = 1,10-phenanthroline) have been synthesized under solvothermal condition, and characterized by elemental analysis, and infrared spectroscopy, X-ray single-crystal and power diffraction analyses. Both crystal structures of complexes 1 and 2 belong to the monoclinic system with space group P21/c. In the two complexes, abundant weak intermolecular interactions (hydrogen bonds and π···π stacking) make their structure more stable. The thermal decomposition of the complexes was also studied by TGA techniques. Moreover, the solid-stated luminescent spectrum of complex 1 shows the obvious emission peak at 438 nm, and the intensity of the emission peak is stronger than those of free H3L and phen. DFT and TDDFT analyses explain that the fluorescence property of complex 1 derive from the π* - n transition from phen to the adjacent carbonyl of HL2-. Magnetic study reveals that complex 2 exists weak ferromagnetic coupling between manganese(II) centers from 2 K to 300 K.

New insight into two penta-coordinated multinuclear copper(II) single-armed salamo-based complexes

With the reactions of a single-armed salamo-based ligand H3L and two kinds of copper(II) salts (Cu(OAc)2·H2O or CuCl2·2H2O) in mixed organic solvents, respectively, two penta-coordinated Cu(II) complexes [Cu2(L)(µ-OAc)]·MeOH (1) and [Cu4(L)2Cl2]·EtOH·CH2Cl2 (2) have been successfully constructed. The precise structures of the two Cu(II) complexes obtained by solvent evaporation method are measured by single crystal X-ray diffraction analyses. The di-nuclear complex 1 crystallizes in triclinic space group P-1, where the main structure is compose of two Cu(II) atoms, one completely deprotonated ligand (L)3− unit, one bridged μ-OAc− counter-anion and one crystallized methanol molecule. The tetra-nuclear complex 2 with an inversion center crystallizes in the same space group as 1 and contains four Cu(II) atoms, two fully deprotonated salamo-based ligand (L)3− units, two bridged Cl− counter-anions, one crystallized dichloromethane and one ethanol molecules. Compared to preceding complexes based on other single-armed salamo-based ligands, the structure of complex 2 reported in this work is unique and has never been found in previous literatures. All of Cu(II) atoms in complexes 1 and 2 are penta-coordinated with the geometries of distorted tetragonal pyramid, and the τ5 value of all Cu(II) atoms have been calculated and all results are less than 0.5. Hirshfeld surfaces analyses of complexes 1 and 2 have been established to explain the interactions of crystal structures, and the corresponding two-dimensional (2D) fingerprint plots have been carried out to quantify the intermolecular interactions. In addition, fluorescence properties of complexes 1 and 2 have been investigated.

Complex 1 is a novel triple‐decker symmetrical six‐core cluster structure with twofold axis and inversion center. The Co(II) atoms were sandwiched between the bis(salamo)‐type ligands and possess two different geometries of distorted tetragonal pyramid and octahedron, respectively. Complex 2 possesses a dinuclear structure and the Ni(II) atoms are located in the N2O2 cavities of the ligand, and axial coordination atoms come from the coordinated water and pyridine molecules. Both Ni(II) atoms adopt distorted octahedral geometries. The interactions were quantitatively determined by Hirshfeld surfaces analyses of complexes 1 and 2. The coordination ratios were determined by studying the fluorescence properties of complexes 1 and 2. The results of fluorescence titration experiment show that the metals to ligand binding ratios are 6:2 and 2:1 for complexes 1 and 2, respectively.

Assembly, photocatalytic and fluorescence properties of three new coordination complexes of zinc(II) and nickel(II) with two kinds of flexible bis(pyridyl)-bis(amide) ligands

Abstract Three new coordination complexes [Zn(btec)0.5(L1)0.5(H2O)] n (1), [Ni(H2btec)(L1)(H2O)2] n (2), and {[Ni(btec)0.5(L2)(H2O)3]·2H2O} n (3) [H4btec = 1,2,4,5-benzenetetracarboxylic acid), L1 = N,N′-bis(3-pyridyl)adipamide, L2 = N,N′-bis(3-pyridyl)octanediamide] have been obtained under hydrothermal conditions. Single-crystal X-ray diffraction analysis has revealed that complex 1 has a layer structure based on [Zn(btec)0.5] n ribbons and the μ 2-bridging ligands L 1 . Complex 2 possesses a layered framework constructed by [Ni(H2btec)] n linear chains and [Ni(L1)] n wave-like chains. Complex 3 forms layers based on [Ni(L2)] n helical chains and μ 2-bridging L2 ligands, representing an interesting 4-fold interpenetrating 2D braided framework. The three different 2D frameworks exhibit 3,4-connected {4.62}2{42.62.82} topology for 1, 4-connected {44.62} topology for 2 and 3-connected {63} topology for 3. Their adjacent layers are further linked by hydrogen bonding interactions to generate 3D supramolecular structures. The differences in the nature of both the metal ions and the organic ligands lead to various coordination modes in the final structures. The photocatalytic activities and the fluorescence properties of complexes 1–3 were investigated.

Synthesis, structure and property of two d-f heteronuclear Eu-TM (TM = Zn and Cd) complexes with open-chain ether Schiff base ligand

Two heteronuclear Zn-Eu and Cd-Eu complexes with open-chain ether Schiff base ligand (bis(5-bromine-3-methoxysalicylidene)-3-oxapentane-1,5-diamine (H2L) and isonicotinate (IN), with composition [Zn2EuL2(OAc)(IN)](NO3)•(CH2Cl2) (1) and {[CdEuL(IN)(OAc)(NO3)(CH3OH)]•3(CH2Cl2)}n (2), have been synthesized and characterized. The structure analysis reveals that the Zn-Eu complex is heterotrinuclear cluster and lanthanide ion acts as a joint bridging of two Zn-L coordination units, whereas the Cd-Eu complex is infinite 1D zigzag coordination polymer formed by Cd-Eu-L secondary units through bridging of isonicotinate. Fluorescence properties of complexes 1–2 in the solid state and DMF solution at room temperature were studied. It has been found that the emission spectra of complexes 1–2 do not exhibit corresponding EuIII ion characteristic emission bands and the fluorescence properties of complexes 1–2 are different due to the introduction of different transition metal ions. Antioxidant properties of the ligand and complexes 1–2 were also studied, the results showed that the ligand and complexes 1–2 display high scavenging activity against hydroxyl (OH•) and superoxide (O2−•) radicals, and the order of the activity is complex 2 > complex 1 > H2L. Therefore, the structures and properties of d-f heteronuclear complexes can be adjusted by selecting different transition metal ions such as ZnII and CdII ions.
