摘要A new three-dimensional (3D) coordination polymer, [Cd(L)2H2O]n·5nH2O 1 with 4-[(3-pyridyl)methylamino]benzoate acid (HL),has been synthesized by slow evaporation solvent at room temperature, and structurally characterized by elemental analysis, IR spectrum, thermal analysis, fluorescence spectrum and single-crystal X-ray diffraction. Compound 1 crystallizes in the tetragonal system, space group I-4, with α = 20.7937(16), c = 13.515(2), V = 5843.5(11) Å3, C26H34CdN4O10, Mr = 674.97, Dc= 1.534 g/cm3, μ(MoKα) = 0.808 mm-1, F(000) = 2768, Z = 8, the final R = 0.0276 and wR = 0.0691 for 5323 observed reflections (I > 2σ(I)). The result of thermal analysis shows that 1 is stable under290 ℃. Moreover, it exhibits blue photoluminescence at room temperature.
