| 摘 要： | A new μ-chloro-bridged one-dimensional coordination polymer [Cd（dmbpy）Cl2]a （dmbpy = 4,4＇-dimethyl-2,2＇-bipyridine） has been synthesized and structurally characterized by elemental analyses, IR, UV spectra and single-crystal X-ray diffraction. The complex crystallizes in the monoclinic system, space group C2/c with a = 17.745（4）, b = 10.326（2）, c = 7.3382（15）A, β = 106.85（3）°, V = 1286.9（4）A^3, Z = 4, C12H12N2Cl2Cd, Mr = 367.54, Dc = 1.897 g/cm^3, F（000） = 720, 2（MoKα） = 0.71073 A,μ= 2.089 mm^-1, R = 0.0368 and wR = 0.1048 for 1041 observed reflections （I 〉 2σ（I））. Cadmium（Ⅱ） adopts a distorted octahedral coordination geometry and adjacent coordination chains are intercalated in a zipper-like fashion into 2D layers through the π-π stacking interactions between dmbpy. Fluorescent analyses show that it exhibits intense blue photoluminescence in both DMF and DMSO solutions at room temperature.
