Abstract

M. T. H. Tarafder and Lee W. Fong

Several novel organodioxygen complexes, [M(O)(O2)2 L] [M=Mo(VI)] and [M'(O2)L] [M'=Cd(II) and Zn(II) and Zn (II)] have been synthesized containing monodentate, bidentate and tridentate ligands. [L=pyridine ,picolinic acid, diethylenetriamine, 1, 2-phenylenediamine, triphenylphosphine oxide]. These complexes were characterized by elemental analyses conductivity measurements, infrared, Raman spectral studies. The v (O=O) stretches of the superaxo complexes were only Raman active, because of apparent linearity of the M-O2 moieties, giving peaks at 1020-1030 cm-1. The complexes were all thermodynamically stable and the complexes containing didentate ligands were found to undergo oxygen transfer reactions to various organic and inorganic substrates. Mechanism have been postulated.
