Abstract

Oxygenation of ruthenium(III) Schiff base complexes of the composition K[RuIII(Saloph)Cl2] and [RuIII(Saloph)XCl] (Saloph=bis(salicylaldehyde)-o- phenylenediamine; X=imidazole (Im), 2-methylimidazole (2-MeIm)) with molecular oxygen gives the oxo derivatives of the composition, [RuV(Saloph)X- (O)]+ (X=Cl, Im or 2-MeIm). The oxo complexes were also synthesized by the reaction of [RuIII- (Saloph)XCl] with PhIO or H2O2. The complexes thus obtained were characterized by analytical data, molar conductance, magnetic susceptibility, spectroscopic and electrochemical methods. Kinetics of the oxygenation reaction have also been investigated.
