OPEN ACCESS
A new Schiff base, derived from isatin and an amino acid, aspartic acid, and its complex with Zinc(II) were synthesized. The formation of Schiff base and its Zn(II) complex were characterized and confirmed by elemental (C,H and N) analysis; molar conductance, magnetic measurements; and FT-IR and UV-VIS spectroscopic methods. From the electronic spectral and molar conductance data, four - coordinated tetrahedral geometry was assigned to the synthesized complex. In addition, the redox behavior of the complex was investigated using cyclic voltammetry technique. The redox properties were scrutinized with nitrogen as well as aerobic atmospheres. The redox process was measured to follow one electron reversible mechanism. The electrochemical properties of the complex have not been affected by the atmospheric conditions due to the non-reactivity of the complex with atmospheric gases like CO2 and O2.
