1,4-对苯二甲酸根桥联的镉髤配位聚合物研究(英文)

Terephthalate Derivatives as Links in the Construction of Two Novel Cd(Ⅱ) Coordination Polymers

使用2-溴-1,4-对苯二甲酸和2-氨基-1,4-对苯二甲酸为配体,在溶剂热条件下得到了两个结构新颖的化合物Cd(BrBDC)(py)(1)和Cd(NH2BDC)(H2O)(2)。单晶结构测试表明:化合物1中,Cd(Ⅱ)离子之间通过羧基连接成一维链,链与链之间通过配体连接成二维平面。化合物2中,Cd髤离子之间通过羧基连接成砖块结构的二维层,层与层之间通过氨基连接成三维结构。对化合物的荧光性质进行了表征。

Two novel cadmium coordination polymers： Cd（BrBDC）（py） （1） and Cd（NH2BDC）（H2O） （2） （BrBDC=2- bromo-1,4-benzenedicarboxylate, NH2BDC =2-amino-1,4-benzenedicarboxylate, py =pyridine）, were synthesized under solvothermal conditions. The crystal structure of Cd（BrBDC）（py） is based on infinite chains of carboxylato- bridged six coordinated Cd（Ⅱ） ions that are linked via the BrBDC ligands to form a 2D structure. Cd（NH2BDC） （H2O） is based on brick-like 2D layers constructed by carboxylato that are crosslinked by the amino groups into a 3D structure. The photoluminescence of both compounds are studied.
