Synthesis, Characterization, and Corrosion Inhibition Assessment of Three New Mononuclear Hybrid Complexes Based on Schiff (2-(2-Hydroxybenzylidene)amino)phenol and Triphenylphosphine Ligand.

ABSTRACT: In this study, we describe the synthesis and characterization of the mononuclear complexes [CuL-(P-(Ph) ₃)]²⁺, [NiL-(P-(Ph) ₃ )-Cl ₂], and [CoL-(P-(Ph) ₃ )-Cl ₂], where L = (2-((2-hydroxybenzylidene)-amino)-phenol). The structural analysis of these complexes was carried out utilizing mass spectrometry, ¹H NMR, ¹³C NMR, ³¹P NMR, UV-visible, and FT-IR. All three complexes were investigated as corrosion inhibitors for mild steel in 1 M HCl. Stationary and transient electrochemical methods were used to evaluate their anticorrosion performance. In addition, the comparison of the three representation planes (Nyquist, Bode, and Betova) guided us in selecting
