以4,5-二氰基咪唑(HIMDN)配体,用常温扩散法合成了2个新颖的金属-有机配合物{[Zn2(IMDN)4(H2O)3].(H2O)3}n(1)和[Co(IMDN)2(H2O)2]n(2),并通过元素分析、红外分析、热重分析和X-射线单晶衍射对其进行了表征。结果表明配合物1中2个中心Zn(Ⅱ)离子的配位环境不同,一个是四配位,另一个是六配位。配合物2的中心钴(Ⅱ)离子为六配位。2个配合物都为一维链状结构,并且均通过氢键作用显示出三维结构。此外还研究了配合物1的荧光性质。
Two novel metal-organic complexes {[Zn2 (IMDN) 4 (H2O) 3] (H2O) 3} n (H2O) were synthesized from 4,5-dicyanoimidazole (HIMDN) 1) and [Co (IMDN) 2 (H2O) 2] n (2) were synthesized and characterized by elemental analysis, infrared analysis, thermogravimetric analysis and X-ray single crystal diffraction. The results show that the coordination centers of two Zn (Ⅱ) ions in complex 1 are different, one is tetracoordinate and the other is hexacoordination. The center cobalt (Ⅱ) ion of complex 2 is hexacoordination. Both complexes are one-dimensional chain structures, and all show three-dimensional structure through hydrogen bonding. In addition, the fluorescence properties of complex 1 were also studied.
