摘　　要：A coordination polymer, [Cd（cpna）（py）]n （H2cpna = 5-（2＇-carboxylphenyl） nicotic acid, py -- pyridine） 1 has been hydrothermally synthesized and characterized by elemental analysis, IR, TG, fluorescence spectra and single-crystal X-ray diffraction. Colorless crystals crystallize in the monoclinic system, space group P21/c with a = 8.589（2）, b = 13.047（3）, c = 14.940（4） A, fl = 96.001（2）°, V = 1664.9（7） A3, C18H12CdN204, Mr = 432.70, Dc = 1.726 g/cm3, F（000） = 856, Z = 4, p（MoKa） = 1.337 mm^-1, the final R = 0.0396 and wR = 0.0891 for 2422 observed reflections （1 〉 2a（I））. Complex I exhibits a two-dimensional （2D） sheet structure, which further builds a three-dimensional （3D） supramolecular architecture via C-H...O hydrogen-bonding interactions.A coordination polymer, [Cd（cpna）（py）]n （H2cpna = 5-（2＇-carboxylphenyl） nicotic acid, py -- pyridine） 1 has been hydrothermally synthesized and characterized by elemental analysis, IR, TG, fluorescence spectra and single-crystal X-ray diffraction.
