由对苯二甲酸构筑的铽三维聚合物的合成和晶体结构

Synthesis and Crystal Structure of A 3D Tb Polymer Constructed by p-Phthalic Acid

使八水硫酸铽与对苯二甲酸(HOOCC_6H_4COOH)在N,N-二甲基甲酰胺(DMF)和甲醇的混合溶剂中反应,采用挥发法,合成了一个三维的配位聚合物[Tb_2(OOCC_6H_4COO)_3]·DMF·4H_2O。采用元素分析、红外以及X-射线单晶衍射进行了结构表征。晶体结构测试表明:在此配合物中,Tb(III)通过对苯二羧酸配体的桥连形成了一个新颖的三维结构。

By the reaction of Tb2（ SO4）3·8H2O with p- phthalic acid（ HOOCC6H4COOH） in N,N- dimethylformamide（ DMF） and methanol solution,a novel three- dimensional coordination polymer,[Tb2（ OOCC6H4COO）3]·DMF·4H2O was prepared. Its structure was confirmed by X- ray structural diffraction,elemental analysis and IR data. The structure determination reveals that each o- OOCC6H4COO2-anion in the complex acts as a tridentate fashion bridging the Tb（ III）ions forming the 3D polymer.
