One two-dimensional coordination polymer with a formula of {[Cd(L)(imidazole)-(H2O)](H2O)}(n) (1) was obtained by the synthetic reactions in aqueous solution using a newly synthesized H2L (H2L = methyl-3-hydroxy-5-carboxy-2-thiophenecarboxylate) ligand. Compound 1 crystallizes in monoclinic system, space group C2/c with a = 18.3176(11), b = 8.5366(9), c = 8.4152(5) angstrom, beta = 101.789(6)degrees, V = 2797.1(3) angstrom(3), D-c = 1.979 g/cm(3), C10H12N2O7SCd, M-r = 416.68, F(000) = 1648, mu = 1.745 mm(-1), F(000) = 1648, the final R = 0.0323 and wR = 0.0604 for 2604 observed reflections with I > 2 sigma(I). Structure analyses reveal that the compound is constructed by dinuclear Cd(II) clusters bridged by two hydroxyl oxygens of L2- anions, which features a two-dimensional network with 4-connected sql topology. Furthermore, the compound exhibits high thermal stability and intense fluorescent emission, and could be explored for potential luminescent materials.
