Spectroscopic and Biological Studies on Newly Synthesized Cobalt (II)‎ and Nickel (II)‎ Complexes with 2-Acetyl Coumarone Semicarbazone and 2-Acetyl Coumarone Thiosemicarbazone

Abstract EN

Co(II) and Ni(II) complexes of general composition ML2X2 (M = Co(II), Ni(II); X = Cl−, NO3 −) were synthesized by the condensation of metal salts with semicarbazone/thiosemicarbazone derived from 2-acetyl coumarone.

The ligands and metal complexes were characterized by NMR, elemental analysis, molar conductance, magnetic susceptibility measurements, IR, and atomic absorption spectral studies.

On the basis of electronic, molar conductance and infrared spectral studies, the complexes were found to have square planar geometry.

The Schiff bases and their metal complexes were tested for their antibacterial and antioxidant activities.
