A new coordination polymer, [Cd2(bptc)(L)2(H2O)2]·5H2O(1, L = 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and H4 bptc = 3,3',4,4'-biphenyltetracarboxylic acid), has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/n with a = 18.868(4), b = 7.2111(14), c = 19.464(4), β = 95.75(3)°, C54H31Cd2Cl2F2N8O15, Mr = 1365.57, V = 2635.0(9)3, Z = 2, Dc = 1.721 g/cm3, S = 1.034, μ(MoKα) = 0.995 mm–1, F(000) = 1358, R = 0.0501 and wR = 0.1076. In 1, each bptc anion bridges four Cd(II) atoms to form 2D layer structures, which are further extended by π-π stacking interactions into a 3D supramolecular architecture. The thermal behavior and luminescent properties of the compound have also been studied. 相似文献
