SYNTHESIS, SPECTROSCOPIC CHARACTERIZATION AND BIOLOGICAL EVALUATION OF MACROCYCLIC SCHIFF'S BASE BENZIL BIS(5-AMINO-1,3,4-THIADIAZOLE-2-THIOL) WITH NI(II), AND CO(II) METAL COMPLEXES
A. Rajput*, S. Gautam, S. Chandra and S. P. Sati
Co (II) and Ni (II) complexes of general composition [ML2]X2 (M = Co(II), Ni(II); X = Cl-, NO3) were synthesized by the condensation of metal salts with semicarbazone / thiosemicarbazone derived from pdimethylaminobanzaldehyde. The metal complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, IR and atomic absorption spectral studies. On the basis of electronic and infrared spectral studies, the metal complexes were found to have tetrahedral geometry. The Schiff bases and their metal complexes were tested for their antibacterial and antioxidant activities.
Keywords: Co (II) and Ni (II) complexes pdimethylaminobanzaldehyde.
