哌酸构筑的孔洞配合物的合成和表征
摘要：哌酸（H2PA）是一种良好的桥联配体。本学位论文工作采用溶剂热法，以哌酸为主要配体，1，2-二(4-吡啶基)乙烯为辅助配体,N，N’-二甲基甲酰胺、乙醇和水为溶剂，设计合成了金属有机配位聚合物 [Cd(C12H10N2)（C23H14O6）（H2O）3/2]n。运用红外光谱对配合物的结构进行了表征，并利用X-单晶衍射仪测定了其晶体结构。结构分析表明，结构单元中存在7配位和6配位两种不同配位模式的Cd(II)离子。Cd(II)离子在哌酸根与1，2-二(4-吡啶基)乙烯配体桥联作用下，形成是三维孔洞结构。

Synthesis and characterization of a porous complex constructed by pamoic acid
Abstract：Pamoic acid (H2PA) is a good bridging ligand in building polymers. In this work, a metal-organic complex [Cd(C12H10N2)（C23H14O6）（H2O）3/2]nwas synthesized using solvent thermal method, derived from pamoic acid ligand in the existence of the auxiliary ligand 1-2 (4-pyridinyl) ethylene. The complex was characterized by IR spectrum and X-ray single- crystal diffraction. Structure analyses show that there are two modes of Cd (II) ions with six and seven coordination number respectively. Cd (II) ions were connected by two carboxylate ligands and two 1,2-Di(4-pyridyl)ethylene bridging ligands, forming a three-dimensional porous structure.
Key words: pamoic acid, 1,2-Di(4-pyridyl)ethylene，IR spectrum， crystal structure
