Abstract

The invention discloses a carbonyl cobalt complex with a three-legged ligand and a preparation method of the carbonyl cobalt complex. The carbonyl cobalt complex has the molecular formula of C19H21ClCoN5O8 or [Co(mapa)(O2CO)]ClO4.H2O, wherein mapa refers to (6-amino-2-pyridylmethyl)bi(2-pyridylmethyl)amine. The structural formula of the carbonyl cobalt complex is shown in a formula (I). The preparation method comprises the following steps: adding [Co(H2O)6](ClO4)2, a three-legged ligand mapa and NaHCO3 into a mixed solvent of H2O and methanol, thereby obtaining a mixed solution; and (2) performing air foaming on the mixed solution, stirring and reacting, performing recrystallization separation on the reaction product, thereby obtaining the carbonyl cobalt complex. The carbonyl cobalt complex and the preparation method thereof provide an important research object for research on coordination chemistry and have extremely high academic value. The structural formula is as shown in the specification.
