| Abstract: A coordination polymer {[Ni(H2BCPBA)2(H2O)4]}n (1, H3BCPBA=3,5-bi(4-carboxy-phenoxy)-benzoic acid) has been synthesized from H3BCPBA by using hydrothermal method and structurally characterized by elemental analysis, IR spectrum, UV spectroscopy, TG and single-crystal X-ray diffraction. Single-crystal X-ray analysis reveals that the coordination polymer 1 is crystallized in the triclinic system, space group P1. The Ni(Ⅱ) ion is six-coordinated by two oxygen atoms from H2BCPBA- ligand and four oxygen atoms from water molecules, generating a octahedral coordination geometry. UV spectroscopy study reveals that the coordination polymer exhibits strong ultraviolet absorption in the solid state at room temperature. CCDC: 837882. |
