Synthesis and Properties of Transition Metal Complexes Containing Thiazole Derived Schiff Base Ligands

Abstract

Although ligands containing four donor atom are tetradentate ligand of Thiazole moiety which coordinated with transition metal ions. The complex of m-NTA and m-MTA are studies by different spectral technique. Here we are synthesizing the thiazole derivatives Schiff base as a ligands, L1 = N,N'E,N,N'E)-N,N'-(1,3- phenylene bis (methanylylidene) bis (5-nitrobenzo [d] thiazo L2-amine (NTA) and L2 = N,N'E,N,N'E)-N,N'-(1,3-phenylene bis (methanylylidene) bis (5-methyl thiazo L2-amine (MTA), and coordinated with transition metals ( Co, Ni, Cu, Zn, and Cd) using lone-pair coordination method. These synthesized complexes were identified by FT-IR spectra, UV-Visible spectra, mass spectra and cyclic voltammetry and having characteristic absorption and potential high-performance CV which show a different type of stable transition metal complex. The electrochemical study was also carried out for these complexes which show the clear redox behaviour of complexes. The significant change in CV properties is exhibited by CV graphs where we can see a prominent reduction peaks M (II) to M is showing at -0.4 V . We found that in the case of L2 there is less prominent reduction peaks observed in comparison to L1.
