For instance, the stability of these complexes plays an important role in many metabolic and toxicological functions. In this work, we introduce two new families of mixed ligand transition metal complexes, M (II & III) sulfate, with nitrilotriacetic acid as a primary ligand and glutamic acid or guanidine as a secondary ligand.enThesis
