Synthesis, structural investigations and corrosion inhibition studies on Mn(<scp>ii</scp>), Co(<scp>ii</scp>), Ni(<scp>ii</scp>), Cu(<scp>ii</scp>) and Zn(<scp>ii</scp>) complexes with 2-amino-benzoic acid (phenyl-pyridin-2-yl-methylene)-hydrazide

Abstract

Metal complexes of 2-amino-benzoic acid (phenyl-pyridin-2-yl-methylene)-hydrazide are synthesized and the structures are determined by X-ray crystallography. These compounds show appreciable corrosion inhibition efficiency for mild steel in 1 M HCl.
