Abstract

Thiacetazone ligand and Sb(III) complex were synthesized by condensation process. The ligand and complex were characterized using melting point, Fourier Transform¬ Infrared (FTIR), Ultraviolet-Visible (UV-Vis), CHNS Analysis, Molar Conductivity and Gravimetric Analysis. The corrosion inhibitor study for ligand and complexes were also conducted. The complex was assigned the formula [Sb(TAC)3]Cb. The melting point of ligand was around 229 - 332 °C and for the complex was around 218 - 220 °C. In the [Sb(TAC)3]Cb, the ligand act as bidentate through N,S-bidentate coordination. For FTIR, the coordination of ligand via the major shifting of (C-N) and thionic (C=S). The UV-Vis shows two types of transition in both ligand and complex which are π→ π* and n → π* transitions. The calculated percentage of Sb(III) in the complex was 11.4 % and the molar conductivity of complex was 3: l electrolyte. For anti-corrosion, ligand shows better inhibitor efficiency in H2SO4 at 0.1 M concentration compared to HCl. Meanwhile, the inhibitor efficiency for the complex in H2SO4 at 0.001 M concentration shows better efficiency compared to HCl.
