Synthesis and Characterization of Cobalt(III) Octahedral Complexes with Flexible Salpn Schiff Base in Solution. Structural Dependence of the Complexes on the Nature of Schiff Base and Axial Ligands

For a long time tetradentate Schiff base complexes of transition metal ions have attracted many researchers interest in the field of coordination chemistry.1-5Co(III) complexes of Schiff base are an important class of coordination compound not only because of them being interesting B12 models and oxygen carriers but also due to their interesting magnetic properties, spectroscopic characteristics and the interaction of metal-to-ligand bonds.4-9
