| 摘要: 水热法合成了2个配合物{[Cu2(L)2(tp)]·2H2O}n (1)和[CuL(ClO4)]n (2)(L=4-羧酸-2,2':6',2"-三联吡啶,H2tp=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。 |

| Abstract: Two new Cu(Ⅱ) coordination compounds, {[Cu2(L)2(tp)]·2H2O}n (1) and[Cu(L)(ClO4)]n (2) (L=4'-carboxy-2,2':6',2"-terpyridine, H2tp=terephthalic 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 triclinic 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. |
