preparation and spectroscopic characterization of some novel schiff base complexes of pd rh and ru

A series of Schiff involving benzoin or 2-( l-hydroxy-2 - acetonaphthol) and thiosemicarbazone, 0,0- phenylenediamine, aniline or 0- bromoaniline and some of their palladium (II), rhodium (III) and ruthenium (II) complexes was prepared. Spectroscopic characterization of the prepared Schiff bases and their complexes were achieved. The spectrochemical parameters (I OOq, B, j3 35) and the ligand field stabilization energy (LFSE) of some of the prepared complexes were calculated. The redox behavior of one of the prepared palladium (II) complexes was investigated employing bulk voltammetry in N, N'- dimethylformamide at different sweep rate.
