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.
The Co (NH2C6H4COO) 2 · (H2O) 4 single crystal with rich hydrogen bond was synthesized by using Co as center metal ion and p-aminobenzoic acid as ligand. The IR, UV-VIS-NIR spectra And determined by X-ray four-circle diffractometer to determine its crystal structure from the structural analysis shows that the crystal is rich in hydrogen bonds molecules into a three-dimensional infinite network structure, and then formed by the hydrogen bond And the coordination of supramolecules. And discussed the formation of hydrogen bonds on the infrared spectrum.
