Two cobalt coordination polymers [CoII2(ida)2(H2O)2]n (1) and [Na2CoIII2(ida)4(H2O)4]n·2nH2O (2) (H2ida = iminodiacetic acid) have been synthesized and characterized by single-crystal X-ray diffraction analysis. Compound 1 exhibits a two-dimensional framework, in which two cobalt atoms exhibit different coordination environments: one is equatorially coordinated by two ida ligands, while another is
合成了两种钴配位聚合物 [CoII2(ida)2(H2O)2]n (1) 和 [Na2CoIII2(ida)4(H2O)4]n·2nH2O (2) (H2ida = 亚氨基二乙酸) -晶体X射线衍射分析。化合物1呈现二维骨架,其中两个钴原子表现出不同的配位环境:一个由两个ida配体赤道配位,另一个由两个水分子和四个ida配体配位。最有趣的是,在化合物 2 中,ida 配体表现出不同的配位模式。有机配位阴离子 [CoIII(ida)2]- 通过钠离子连接形成二维层。
