| Summary: | <strong>ABSTRACT:</strong><br /> The work included the preparation of cobalt complexes having general formula [ CoL] , where L is divalent tetradentate Schiff base ligand derived from benzyl and anthranilic acid or o-aminophenol with 1:2 molar ratio . These complexes reacted with H<sub>2</sub>O<sub>2</sub> in the absence and in the presence of B (B= py , -pic , Pph<sub>3</sub>) at room temperature to obtain [ CoLO<sub>2</sub> ] and [CoLBO<sub>2</sub> ] complexes. All the prepared complexes were characterized by metal content analysis , molar conductance , spectral studies including I.R and electronic spectra as well as magnetic measurements. These studies revealed that all the complexes are non-electrolytes. The Schiff base ligands act as dibasic tetradentate ( NNOO-donor) , CoL complexes are square planar containing one unpaired electron. The electronic spectra reveals the oxidation of Co(II) to Co(III) in [CoLO<sub>2</sub>] and [CoLBO<sub>2</sub>] complexes. These complexes show μ<sub>eff</sub> values related to one unpaired electron , that belongs to O<sub>2</sub> mioety , which is supported by (υ<sub>o-o</sub>) band in I.R spectra that related to O<sub>2</sub> mioety. Hence superoxo compounds are realy recognized. |
