Synthesis, StructuralCharacterization And Antimicrobial Activities of Fe(II), Co(II) and Ni(II)Schiff Base Complexes Derived From L-Arginine and Benzaldehyde


Abstract Fe(II), Co(II) and Ni(II) metal complexes with newSchiff base derived from L-arginine and Benzaldehyde have been synthesized andcharacterized based on their conductivity measurements, elemental analysis,infrared and electronic spectra. The spectral analysis reveals that the ligandacts as a bidentate molecule coordinating through the nitrogen atom of theazomethine group and the oxygen atom of the carboxylate group forming chelateswith 1:2 metal to ligand stoichiometry. The complexes of Fe(II) and Co(II) werefound to be tetrahedral whereas that of Ni(II) was proposed to be squareplanar. Antimicrobial activities of the Schiff base ligand and their metalcomplexes reveal that the Schiff base transition metal complexes showsignificant inhibitory activities against some fungi and bacteria.
