摘 要: | A new metal-organic complex Zn2(cbba)4(phen)2 (Hcbba = 2-(4′-chlorine-ben-zoyl)benzoic acid, phen = 1,10-phenanthroline) 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. The compound crystallizes in orthorhombic, space group Pbcn with a = 12.0821(11), b = 18.3140(17), c = 30.961(3), V = 6850.7(11)3, C80H48Cl4N4O12Zn2, Mr = 1529.76, Dc = 1.483 g/cm3, μ(MoKα) = 0.925 mm?1, F(000) = 3120, Z = 4, the final R = 0.0559 and wR = 0.1146 for 3963 observed reflections (I > 2σ(I)). In the crystal structure, the zinc atom is five-coordinated with three carboxylate oxygen atoms from three different cbba ligands and two nitrogen atoms from the phen ligand, showing a distorted square-pyramidal geometry. Furthermore, it exhibits a 3D supramolecular network through π-π interactions and shows yellow photoluminescent property at room temperature.
