具有共轭体系的吡啶基羧酸是一类重要的有机配体,其过渡金属配合物在酶模拟、医药、催化和磁性等功能材料等方面均具有潜在的应用前景。将硝酸钴、邻菲罗啉(Phen)和3,4-二羧基吡啶(Pydc)按1∶2∶1物质的量比计量,在pH=5和50-60℃加热搅拌的条件下,在甲醇溶液中合成了钴(Ⅲ)的三元配合物,用元素分析、红外光谱、紫外光谱、热重分析和摩尔电导率对配合物进行表征,结果表明该配合物为1∶1型电解质,其组成为[CoⅢ(Pydc)(phen)2]NO3.H2O,其中Pydc=C7H3O4N。
Pyridinecarboxylic acids with conjugated system are an important class of organic ligands. Their transition metal complexes have potential applications in enzyme modeling, functional materials such as medicine, catalysis and magnetism. The cobalt nitrate, phenanthroline and 3,4-dicarboxypyridine (Pydc) were metered in a mass ratio of 1: 2: 1 substance and the mixture was stirred under stirring at pH = 5 and 50-60 ° C for The ternary complex of cobalt (Ⅲ) was synthesized in methanol solution. The complex was characterized by elemental analysis, IR, UV, TG and molar conductivity. The results showed that the complex was a 1: 1 type electrolyte, Its composition is [CoⅢ (Pydc) (phen) 2] NO3.H2O, where Pydc = C7H3O4N.
