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

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.
