IR, Electronic, Thermal, Cyclic Voltammetric, and Computational Studies on Ferric(III) Albendazole Complex

Preparation, spectroscopic characterization, electrochemical studies, and theoretical calculations of albendazole (Albz) and its mononuclear ferric(III) complex, [Fe(Albz)(Cl)3(H2O)], are described. Based on infrared and electronic spectra as well as magnetic measurements Albz molecule seems to be a neutral bidentate ligand via carbonyl group and NH of five-member ring with octahedral fashion toward Fe(III) ions. The thermogravimetric analysis confirms the presence of water molecules existed inside the coordination sphere. The kinetic parameters were estimated and gave an idea about the stability of ferric(III)–Albz complex dependent of TG–DTG curves.
