Synthesis, Spectral Characterization and Electrolytic Nature of Cu(II) Complexes of Azo-Carboxylate Ligands
Manojit Roy*, Keisham Surjit Singh

Six new Cu(II) complexes of azo-carboxylate ligands were synthesized using 1:1 and 1:2 metal-ligand stoichiometric ratio. The complexes were characterized by UV-visible and IR spectroscopy in combination with elemental analysis. The electrolytic nature of the complexes was determined by conductivity study. IR spectroscopy study indicated that the carboxylate ligands act as bidentate mode of coordination through the carboxylic oxygen atoms. UV-visible spectral study suggested four coordinate square planar geometry of the complexes in the solution state.
