Abstract

In this study, the electrochemical behaviour of the ligand ((1,3,5-triazine-2,4,6-triyl)tris(azanetriyl))hexamethanol (H6L) and its complexation with Mn(II) ions was reviewed using cyclic voltammetry and thermodynamic studies. The ligand showed one oxidation peak in a KCl solution with an irreversible system. The binding interactions between ligand and manganese chloride were examined by monitoring the shifts in redox potential and peak current, providing the complex formation. The introduction of catechol is a significant to the electrochemical response of Mn (L) complex. The most stable ratio in solution was 3:1 metal : ligand. Thermodynamic analyses showed that the formation of the complex in solution was further investigated using parameters such as the stability constant (βj) and Gibbs free energy (ΔG), revealing a stable 3:1 metal-to-ligand molar ratio for the Mn (L) complex.
