| Abstract: A one-dimensional cadmium(Ⅱ) complex [Cd(BDC)(H2C2EIm)(H2O)]n with 1,4-benzenedicarbo-xylic acid(BDC) and 2,2′-(ethanediyl)bis(1H-benzimidazole) (H2C2EIm) has been synthesized by means of hydrothermal method and characterized by elemental analysis, thermal analysis, IR spectroscopy and X-ray single-crystal diffraction. The crystal is triclinic, space group P1 with a=10.307(5) nm, b=10.907(5) nm, c=11.934(5) nm, α=63.021(5)°, β=73.308(5)°, γ=79.423(5)°, V=1.143(9) nm3, Dc=1.618 g·cm-3, Z=2, F(000)=560, Goof=1.027, R1=0.023 3, wR2=0.061 7. The complex shows a one-dimensional (1D) zigzag chain structure and further extends into a 3D supramolecular structure through N-H…O, O-H…O hydrogen bonding interactions. Luminescent studies show that the complex exhibits intense blue fluorescent emission. CCDC: 802048. |
