Four novel antimony(III) compounds (SbX3; X = Cl or Br) of thiourea derivatives; N-methylthiourea (NMTU)  and N-ethylthiourea (NETU) of formulae [SbCl3(NMTU)3] (1), [SbBr3(NMTU)3] (2), [SbCl3(NETU)3] (3) and [SbBr3(NETU)3] (4) were synthesized. These new antimony(III) halide compounds were characterized by melting point, elemental analysis, molar conductivity, FT-Infrared spectroscopy, FT-Raman spectroscopy, UV-Vis spectroscopy, NMR (1H and 13C) spectroscopy and TG-DTA analysis. The reactions of N-methylthiourea (NMTU) and N-ethylthiourea (NETU) with SbX3 (X = Cl or Br) in a 2:1 ligand/metal rate but unexpectedly products were formed in a 3:1 ligand/metal rate. The compounds are non-electrolytes in solution and spectroscopic data of the compounds are appropriate with six coordinate octahedral geometry by three halide ions and three sulfur atoms from thiourea ligands. N-methythiourea and N-ethylthiourea ligands behave as monodentate in compounds 1-4 with the binding through sulfur.  The influence of these compounds 14, N-methythiourea and N-ethylthiourea upon the catalytic peroxidation of linoleic acid to hyperoxolinoleic acid by lipoxygenase was kinetically studied.
