一例新颖刚性双咪唑锌配合物的合成及晶体结构

Synthesis and Crystal Structure of a Novel Zinc Complex Containing Imidazole Ligand

以刚性双咪唑配体1,4-对苯二咪唑(bib)、硝酸锌、硝酸,水为起始原料,采用水热法合成了一例新颖的二维互穿的锌配合物[Zn(bib)_2]·2NO_3-(1),并通过单晶X-射线衍射技术测定了其晶体结构。测试结果表明:该配合物为单斜晶系,C2/c空间群,晶胞参数a=20.0312?,b=12.7986?,c=19.8453?,β=100.538°,V=5002.02?~3,Z=8。

A novel two-dimensional interpenetration complex, [Zn（bib）2]·2 NO3-（1） was synthesized under hydrothermal conditions by using rigid imidazole ligand 1,4-bis（imidazol-1-yl）benzene（bib）, Zn（NO3）2, HNO3 and water as raw materials. Single-crystal X-ray diffraction analysis revealed that the complex crystallizes in the monoclinic, C2/c space group, with a=20.0312 ？, b=12.7986 ？, c = 19.8453 ？, β=100.538°, V=5001.95 ？~3, Z=8.
