Synthesis and study of complexes of tetradentate Schiff base and bridging ligand of thiocyanate with transition metals of Fe, Cr and Co

A group of combinations which have more importance in biological studies, biochemistry and also catalytic applications, are schiff base complexes. They have been considered by the chemists. In this research, Schiff base ligand was provided by means of 2,3-diaminopyridine and salicylaldehyde in absolute ethanol solvent with reflux method. Then the complexes of transition metals Fe, Cr and Co with the supplied ligand to being determind synthesized bridging thiocyanate and using FT-IR, cyclic voltammetry (CV) and UV-Vis spectroscopy. The information obtained from cyclic voltammograms of the complexes showed that the electrochemical behavior of the synthesized combinations indicates reversible the state of the complexes. Electrone spectra in the complexes accompanied by axial ligand with due attention to central electron giving ligand feature has decreased or increased transfers intensity which can be confirmed in complex formation.
