摘要
以Co为中心金属离子,对氨基苯甲酸为配体,合成了含有丰富氢键的配合物Co(NH2C6H4COO)2·(H2O)4单晶.对它进行了IR,UV—VIS—NIR光谱的测定,并经X—光四圆衍射仪测定,确定了它的晶体结构.从结构分析可知,该化合物晶体是通过丰富的氢键将分子连接成三维无限网络结构,进而形成了由氢键连接而成的配位超分子.并讨论了氢键的形成对其红外光谱的影响.
Taking p-aminobenzoic acid as ligand, Cobalt as center metal ion, the complex of Co(NH_2C_6H_4COO)_2·(H_2O)_4 with abundant hydrogen bonds has been synthesized. This coordination compound has been characterized by IR, UV-VIS-NIR spectroscopes and single-crystal X-ray diffraction. From its structure, we know that there is a three-dimension hydrogen bond network. Connected with the abundant H-bonds, all the molecules of Co(NH_2C_6H_4COO)_2·(H_2O)_4 form a super molecular coordination compound.
