Abstract:
Newly synthesized Cobalt (III) complexes of thiosemicarbaziones, derived from condensation of 2‐acetyl pyridine or 2‐acetyl thiophene with alkyl and aryl substituted (4N) thiosemicarbazide. The ligands are tridentate and having donor sites N-N-S and S-N-S, respectively. The isolated solid complexes were characterized by elemental analysis, electronic spectra, infrared spectra, 1H NMR spectra, magnetic susceptibilities and molar conductivities measurements. Cyclic Voltametric studies were performed to explain the redox behavior of the complexes. The complexes are low spin with octahedral geometry and found to be diamagnetic. The ligands and isolated complexes were screened for selective antibacterial and antifungal activities and some of them having appreciable amount of antimicrobial activities.
