摘要

合成了一种双核钴(II)配合物[Co2(H2O)4(3-PBIM)4(1,3- bdc)2]·2H2O (1,3- h2bdc = 1,3-苯二甲酸，3-PBIM = 2-(3-吡啶基)苯并咪唑)，并用元素分析、红外光谱和单晶x射线衍射对其进行了表征。晶体独立的钴原子由四个氧和两个氮供体配位成八面体([CoN2O4])。两个钴配位单元([CoN2O4])通过两个1,3- bdc2 -配体的四个羧基氧原子连接在一起，形成一个二金属单元([CoN2O4]2)。广泛的氢键相互作用将双核金属单元连接成三维框架。

A New Binuclear Cobalt(II) Complex Based on 1,3-Benzenedicarboxylic Acid and 2-(3-Pyridyl)benzimidazole

A binuclear cobalt(II) complex, [Co2(H2O)4(3-PBIM)4(1,3-BDC)2]·2H2O (1,3-H2BDC = 1,3-benzenedicarboxylic acid, 3-PBIM = 2-(3-pyridyl)benzimidazole), has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystallographically independent cobalt atom is coordinated by four oxygen and two nitrogen donors in an octahedron geometry ([CoN2O4]). Two cobalt coordination units ([CoN2O4]) are linked together via four carboxyl oxygen atoms of two 1,3-BDC2− ligands, forming a dimetal unit ([CoN2O4]2). The extensive hydrogen bonding interactions connects the binuclear metal units into three-dimensional framework.
