Ten metal complexes of Co²⁺, Ni²⁺, Cu²⁺, Zn²⁺ and Cd²⁺ were synthesized by two novel Schiff bases derived from condensation of m-pthalaldehyde with 4-amino benzoic acid and isonicotinic hydrazide. The as-synthesized metal complexes were characterized and explored by different spectroscopic techniques. FT-IR spectra have confirmed the presence of C=N bands as well as UV–Vis spectroscopy in both Schiff bases KM-1 and KM-2. All as-prepared compounds were evaluated for the antimicrobial activities against the Escherichia coli and Propionibacterium acnes. KM-1 and its metal complexes have shown efficient results compared to KM-2. The electrochemical study of M²⁺ complexes by cyclic voltammograms in electrolyte solution (Pt electrode) demonstrated electrochemically irreversible oxidative and reductive responses.
