ResumoThe oxidation of [VO(salen)][salen =N,N′-ethylenebis(salicylideneiminate)] with iodine produces a mixed vanadium(IV)–vanadium(V) species containing [(salen)VOVO(salen)]+ and the counter ion I5–, as determined by X-ray crystal-structure analysis. The oxidation of related vanadyl Schiff-base complexes produces similar species. Magnetic and spectroscopic properties of these new complexes are described.
