| Abstract: A new zinc(Ⅱ) coordination polymer [Zn(bbmb)(Pht)]n (bbmb=4,4′-bis(benzimidazol-1-ylmethy1)biphenyl, H2Pht=phthalic acid) has been prepared by hydrothermal method and structurally characterized by elemental analysis, IR, PXRD, TGA and single-crystal X-ray diffraction. The title compound crystallizes in monoclinic, space group P21/c with a=1.085 28(10) nm, b=2.286 7(2) nm, c=1.218 53(12) nm, β=102.589(3)°, V=2.951 3(5) nm3, Z=4, and exhibits a 2D network. Fluorescence spectrum studies reveals that the zinc(Ⅱ) complex exhibits strong fluorescence absorption at 416 nm (λmax) in the solid state at room temperature. CCDC: 880548. |
