Abstract

Complexes of Cr(III), Fe(III) and Co(III) with biacetyl mono oxime phenoxy acetyl hydrazone(BAMPxH), bibenzoyl monoxime phenoxy acetyl hydrazone(BBMPxH) have been isolated and characterized by analytical data, molar conductance, magnetic measurement, electronic spectra and thermo–gravimetric analysis. Cr(III), Fe(III) and Co(III) complexes were found to have octahedral structure. This paper describes the preparation and characterization of transition metal complexes of biacetyl monoxime phenoxy acetyl hydrazone (BAMPxH) and bi benzoyl monoxime phenoxy acetyl hydrazone (BBMPxH). The stereo-chemistry of the coordination compounds has been confirmed on the basis of electronic spectral and magnetic moment studies. Racah’s inter-electronic parameter (B), Cubic Ligand field splitting parameter (10Dq) and Nephelauxetic ratio (β), g, λ, h have also been calculated and found that the values are in accordance with the stereo-chemical structure of the coordination compounds. The ligands BAMPxH and BBMPxH are of greater importance since they have ability to chelate metal ion through nitrogen/or oxygen donor centers. Thess ligands can form such type of complexes which are biologically important. Such metal complexes show interesting and important characteristics, especially in areas such as semiconductors, heat resistance materials and gas separators. There has been growing interest for polymeric compounds which are coordinated between ligands and transition metal complexes.
