Electrochemical Study of Benzimidazole Complexes with Copper (II) Ions in Organic Solvents

The electrochemical behaviours of copper (II) benzimidazole complex species have been studied in varying concentrations of benzimidazole using cyclic voltammetry. The cyclic voltammetric parameters were calculated. The complex species described involved two or more redox steps. The first step (Cu2+/+) involved a single electron, diffusion-controlled quasi-reversible electrode process (EC mechanism), while the second step(s) involved an irreversible reduction of the Cu(I) species to metallic copper.
