The crystal and molecular structure of a binuclear cobalt(III) complex with bis-(3-methoxysalicylaldehyde)ethylenedi-imine. Evidence for the bridging ability of some quadridentate Schiff bases

Abstract

Cobalt(III) complexes of general formula Co₂(chel)₃[chel =NN′-ethylenebis(salicylidene- and 3-methoxysalicylidene-iminato)] have been isolated, in which the Schiff base acts both as quadridentate ligand, in a non-planar conformation, and as chelate ligand bridging the two cobalt atoms.
