Synthesis and Spectral Characterization of Nickel (II) and Copper (II) Complexes of 4-Chlorobenzaldehydethiosemicarbazone (CBTSC) and Evaluation of Antioxidant Activity.

摘要

ABSTRACT Para-Chlorobenzaldehyde thiosemicarbazone was used as the bidentate ligand to synthesize nickel(II) and copper(II) complexes. The complexes are characterized by using different spectroscopic techniques like FTIR, FT-Raman and electron paramagnetic spectroscopy. IR and Raman spectral analysis established the coordination of the donor groups of the free ligand with the metal ions. The thermal analysis of these complexes has shown different stages of decomposition with which the strength .
