Abstract
The ligand derived from 4-aminoantipyrine and benzophenone was synthesized and characterized by elemental analysis, IR, electronic spectrum, 1H NMR and mass spectrum. Schiff base complex was synthesized and characterized by elemental analysis, molar conductance, IR, electronic spectra, magnetic measurements and electrochemical studies. Conductance measurements indicate that the complexes are non electrolytes. IR spectral data show that the ligand is bidentate and the binding sites are azomethine nitrogen and carbonyl oxygen atoms. Electronic spectral measurements indicate distorted square planar geometry for Cu(II) complex. Magnetic measurements showed mononuclear and paramagnetic behaviour for Cu(II) complex. The metal complexes are found to be stabilized in the unusual oxidation states of the metal ion during electrolysis.
