Synthesis, Spectral Characterization and Computational Studies of Metal Chelates of 4-N-(2-Thienylidene)aminoantipyrine

Metal chelates of Schiff base derived from thiophene-2-aldehyde with 4-aminoantipyrine have been synthesized. The ligand and the complexes have been characterized by IR, molar conductance, magnetic moments, EPR, cyclic voltammetry, XRD and SEM measurements. Computational studies were also carried out. The geometry of the complexes was investigated by electronic spectral data and magnetic moment measurements. The metal complexes exhibit higher antibacterial activity than the free ligand.
