Abstract
The Schiff base derived from 4-aminoantipyrine and 3-hydroxybenzaldehyde was synthesized and characterized by elemental analysis, IR, electronic, 1H NMR and mass spectrum. Schiff base complex was synthesized and characterized. Conductance measurements indicates the non-electrolytic nature of complex. 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 the paramagnetic behaviour for the complex. The metal complexes are found to be stabilized in the unusual oxidation states of the metal ion during electrolysis. Superoxide dismutase and reducing power activities of the copper complexes have also been studied. Depending on the molecular structure, the complex possess promising SOD mimetic activities.
