“…Metal complexes incorporating Schiff bases have shown and continue to be developed for a wide variety of applications, from catalysis 1,2 to bioactive compounds with typical metal ions used for the bioactive complexes spanning Cu( ii ), Co( ii ), Fe( ii ), and Ni( ii ). 3–6 Non-innocent Schiff base vanadium-catecholates (V-catecholates) have interesting electronic properties with the potential for redox taking place not only on the metal center but also on the ligand.…”
