| Abstract: | In this paper, a new cadmium complex Cd2(hebimc)2(hex)]·2H2O was synthesized using 2-hydroxybenzimidazole-5-carboxylic acid (Hhebimc), hexadiic acid (H2hex) and Cd(NO3)2·6H2O as raw materials. The complex was characterized by X-ray single crystal diffraction, elemental analysis, infrared spectrum, TG, XRD and fluorescence spectrum. The single crystal X-ray diffraction results show that the complex is triclinic, the space group is P1, the central Cd(Ⅱ) has a distorted octahedral configuration, the crystal cell parameters are a=0.860 33(15) nm, b=0.906 59(16) nm, c=1.012 03(18) nm, α=74.826(3)°, β=73.131(3)°, γ=85.128(3)°, V=0.729 0(2)nm3, which is a coordination polymer with three-dimensional supermolecular framework. Fluorescence spectrum analysis shows that the complex has similar luminescent properties to the free ligand. |
