Synthesis, characterization and corrosion inhibition property of nickel(II) and copper(II) complexes with some acylhydrazine Schiff bases

Ni(II) and Cu(II) complexes of 2-amino-benzoic acid (1-phenyl-propylidene)-hydrazide and 2-hydroxy-benzoic acid (1-phenyl-propylidene)-hydrazide have been synthesized and characterized by spectral and X-ray diffraction techniques. The corrosion-inhibition efficiency of the compounds are analysed for mild steel in 0.5 M H2SO4 medium.
