Synthesis, Characterisation and Corrosion Inhibition of Mild Steel by Butyltin(IV) 2-Acetylpyridine 4-Methyl-3-Thiosemicarbazone in HCl
Schiff base ligand, 2-acetylpyridine 4-methyl-3-thiosemicarbazone (Me-LH), and its organotin complex (BuSn(Me-LH)Cl2) were synthesized, characterized, and subjected to corrosion inhibition study. The spectra and crystal structure obtained revealed that the ligand is coordinated by pyridyl nitrogen,...
