Synthesis, characterization, and antimicrobial activity of complexes of Cu(II), Ni(II), Zn(II), Pb(II), Co(II), Mn(II), and U(VI) containing bidentate Schiff base of [S-methyl-3-(4-methoxybenzylidine)dithiocarbazate

Abstract

A novel bidentate Schiff base containing NS donor sequences was synthesized by condensing S-methyldithiocarbazate (SMDTC) with p-anisaldehyde. A series of complexes of the ligand with Cu(II), Ni(II), Zn(II), Pb(II), Co(II), Mn(II) and U(VI) were studied and characterized by various physico-chemical methods. Cu(II), Ni(II) and Zn(II), Pb(II) complexes were four-coordinate with square plannar and tetrahedral geometry respectively. Co(II), Mn(II), and U(VI) complexes were six-coordinate with octahedral geometry. Antimicrobial activity of the prepared complexes was tested as resistance to antimicrobial agents in a wide variety of nosocomial and community-acquired pathogens. The highest antimicrobial activity was detected for the complex Co(II) against candida species.
