摘要：

The solution chemistry of picolinic acid (PA), nicotinic acid (NA), diethylthiocarbamate (Et(2)dtc) ligands and their complexes has been studied by cyclic voltammetry on platinum working electrode and it was observed that the cyclic voltammetric behavior of ligands, binary complexes and mixed ligand complexes are distinctly different. The binary complexes of copper(II) with PA and NA in 1:1 (Cu:PA/NA) molar ratio and their mixed ligand complexes with diethyldithiocarbamate (Et(2)dtc) in 1:1:1, Cu:Et(2)dtc:PA/NA molar ratio in acetone medium was investigated by cyclic voltammetry and UV-Visible spectroscopy. The PA and NA ligand showed irreversible redox couple with Delta E-p values >120 mV. It was observed that mixed ligand complexes exhibits irreversible redox couple in positive potential region due to Cu2+/3+ and Cu3+/2+ change. The electronic absorption spectra of binary complexes showed only one peak in visible region while mixed ligand complexes exhibited two peaks, one in UV region while other visible region.
