配位聚合物[Mn(bpda)(benzidine)]_n的晶体性能研究

Investigation on Crystal Properties of Supermolecular Complex [Mn(C_(14)H_8O_4)(C_(12)H_(12)N_2)]_n

根据文献合成了联苯二甲酸,并通过水热法制备了[Mn(bpda)(benzidine)]n暗棕色的针状晶体。通过X-射线衍射分析、元素分析、IR等方法对配合物进行了表征,并通过TG分析对该配合物的热稳定性及热分解机理做了初步探讨。结果表明,正是基于bpda分子四齿μ3-配位形式,使得该配体的热稳定性要明显高于另一配体联苯胺。

2,2＇-biphenyl-,2＇-dicarboxylate acid was prepared following the literature method and the resulting needle-like orange crystals Mn（C14H8O4）（C12H12N2） was obtained by hydrothermal method.The complex was characterized by Elemental,X-ray diffraction,IR analysis. Based on the TG curve,the thermal decomposition mechanism of the compound has also been discussed. Basd on the bpda group actting as a tetradenate μ3-bridging ligand,the thermal behavior indidates that the bpda group is more stable than the other ligand benzidine.
