Homo- and Heteronuclear Cobalt(III)-Based Complexes with 2-Methoxy-6-[(Methylimino)Methyl]Phenol: Structure and Antioxidant Properties

  • Published:
Theoretical and Experimental Chemistry Aims and scope

CoL3·DMF, [CoCdCl2L3]·0.5H2O, and [CoMnCl2L3]·H2O complexes, where HL is a product of the condensation of o-vanillin and methylamine have been obtained. The crystal structure of the latter complex has been determined by X-ray structural analysis. The study of the antioxidant activity of these complexes in a model reaction of radical-chain oxidation of benzyl alcohol with an atmospheric oxygen has proved a significant inhibition of this process at concentrations of the complexes of 10–7-10–6 mol/L. It is established that the inhibitory activity of the compounds depends on the nature of the metal ions present in the complex.
