Oxidative activation of CoII in Schiff base complexes in the presence of n-butyltin trichloride: the molecular structure of BunSn(OMe)Cl2·CoCl(salen)[salen =N,N′-ethylenebis(salicylideneaminato)]
Abstract
Air stable chloroform solutions of Schiff base complexes of CoII undergo rapid cobalt oxidation on addition of n-butyltin trichloride yielding complexes in which, as exemplified by the crystal structure of BunSn(OMe)Cl2·CoCl-(salen)[salen =N,N′-ethylenebis(salicylideneaminato)], the cobalt(III) Schiff base species behave as Lewis bases towards tin(IV).
