Hydrothermal synthesis and crystal structure of a neutral cyclic tetranuclear cobalt(II)complex with 5-nitrosalicylate and 1,10-phenanthroline ligands

摘要

A novel complex,Co4(phen)4{5-(NO2)sal}4(1)(5-(NO2)sal=5-nitrosalicylate anion,phen=1,10-phenanthroline),have been prepared by hydrothermal synthesis and characterized by single crystal X-ray analysis,IR,TG,cyclic voltammogram and elemental analyses.This complex displays a neutral metallamacrocyclic structure containing[Co(phen)]~(2+)corner units and 5-(NO2)sal bridging ligands.
