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) , β = 96.001(2)°, V = 1664.9(7) 3 , C18H12CdN2O4 , Mr = 432.70, Dc = 1.726 g/cm 3 , F(000) = 856, Z = 4, μ(MoKα) = 1.337 mm -1 , the final R = 0.0396 and wR = 0.0891 for 2422 observed reflections (I > 2σ(I)). Complex 1 exhibits a two-dimensional (2D) sheet structure, which further builds a three-dimensional (3D) supramolecular architecture via C-H···O hydrogen-bonding interactions.
