Potentiometric titration was used to follow the formation of complexes. The complexes formed were studied through the determination of stability constants of these complexes in mixed ethanol-aqueous solution at 25±0.1 °C and ionic strength of 0.1mol⋅dm−3NaCl. The basicity of the ligand was also assessed by the determination of the dissociation constants of the ligand. All of the constants were determined by computer refinement of pH-volume data using the SUPERQUAD program. The species distribution diagrams were also calculated. Comparison with other vic-dioximes was made to provide reliable support for the formation of the proposed complexes in solution.
