Synthesis, Spectroscopic Monitoring and Biological Activities of N₂O₄ Schiff base Ligand containing Metal Complexes of Cd(II), Pd(II), Hg(II) and Zr(IV)

Cd(II), Pd(II), Hg(II) and Zr(IV) complexes of bis(indoline-2-one)triethyelenetetramine which is made from isatin and triethylenetetramine were prepared and characterized by physical properties, spectral and magnetic methods. Based on the analytical results, electronic and infrared spectral data and magnetic susceptibility measurements, suitable structures have been proposed. The formation of the complexes were monitored by UV-Vis spectroscopy. The antimicrobial results indicate that the cadmium complex exhibit more activity than the palladium (II), mercury and zirconium (II) complexes.
