| 摘 要： | The coordination polymer [Ni(dpa)(bpp)]n(H2dpa = 2,4'-biphenyl-dicarboxylic acid,bpp = 1,3-di(4-pyridyl)propane) was hydrothermally prepared and characterized by single-crystal X-ray diffraction,FTIR spectra,elemental analysis and thermal analysis.The crystal is of triclinic system,space group P1 with a = 12.516(5),b = 12.943(5),c = 15.130(5) ,α = 94.331(5),β = 91.827(5),γ = 108.382(5)°,C54H44N4Ni2O8,Mr = 497.18,V = 2315.3(15) 3,Dc = 1.426 g/cm3,F(000) = 1032,μ = 0.875 cm-1,Z = 2,the final R = 0.0496 and wR = 0.1100 for 5365 reflections with Ⅰ 2σ(Ⅰ).X-ray diffraction analysis reveals that the carboxylate group of 2,4'-diphenic acids acting as bridging ligands adopts two coordination modes:bis-mondentate and bidentate chelating.The compound exhibits a two-dimensional(6,3)-connected architecture.
