摘　　要：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）A, β = 95.75（3）°, C54H31Cd2Cl2F2N8O15, Mr = 1365.57, V = 2635.0（9）A3, Z = 2, Dc = 1.721 g/cm^3, 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.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.
