两个基于4-羧酸-2,2′∶6′,2″-三联吡啶的铜配合物的合成、晶体结构及性质（英文）

Syntheses, Crystal Structures and Properties of Two Cu(Ⅱ) Complexes Based on 4′-Carboxy-2,2′∶6′,2″-terpyridine

水热法合成了2个配合物{[Cu_2(L)_2(tp)]·2H_2O}_n(1)和[CuL(ClO_4)]_n(2)(L=4-羧酸-2,2′∶6′,2″-三联吡啶,H_2tp=对苯二甲酸)。对其晶体结构进行了分析,结果表明配合物1和2都通过配体和金属离子组装成一维链结构;配合物1属于三斜晶系,P1空间群,并通过链间的氢键作用形成三维的网状结构;配合物2通过链与链间的氢键作用形成二维的层状结构。对其热稳定性和荧光性质进行了研究。

Two new Cu（Ⅱ） coordination compounds, （[Cu2（L）2（tp）]· 2H2O}n （1） and [Cu（L）（CIO4）]n （2） （L=4＇-carboxy- 2,2＇ ：6＇ ,2＇＇-terpyridine, H2tp=terephthalie acid）, were synthesized under hydrothermal conditions. The structures were characterized by single-crystal X-ray diffraction analyses. The results show that both the complex 1 and 2 display 1D chain structure composed of ligands and metal ions. Complex 1 belongs to trielinic system, space group P1, and it self-assembles into a 3D netlike structure by the inter-chain hydrogen bond interactions and C- H ... π interactions; whereas a 2D layer structure of complex 2 is assembled by hydrogen bonds between the chains. Thermal stability and fluorescent properties of 1 and 2 were also investigated. CCDC： 1428254, 1; 1438989, 2.
