Abstract

CoL3 center dot DMF, [CoCdCl2L3]center dot 0.5H(2)O, and [CoMnCl2L3]center dot 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.
