Abstract

A dinuclear mixed valence cobalt(II/III) complex, [(N3)CoIIIL(µ-CH3COO)CoII(N3)]∙CH3OH with a N2O4 donor compartmental reduced Schiff base ligand, H2L [(1,3-propanediyl)bis(iminomethylene)bis(6-ethoxyphenol)], has been synthesized and characterized by spectral and elemental analyses. Cobalt(III) is placed in the inner N2O2 compartment whereas cobalt(II) is present in the outer O4 compartment of the ligand. Structure of the complex is confirmed by single crystal X-ray crystallography. The magnetic susceptibility measurement confirms that the complex belongs to localized class-I mixed valence system with isolated S = 3/2 ion and shows Curie-Weiss paramagnetism.
