Abstract

Abstract: To investigate the coordination chemistry of the complexes formed by aromatic thiosemicarbazones with main group elements, a number of complexes of benzaldehyde-derived thiosemicarbazone ligands with antimony(III) halides were synthesized. Three new complexes were prepared by the reaction of thiosemicarbazones with antimony(III) halides in 2 : 1 molar stoichiometric ratios. The molecular structures of these complexes were revealed using spectroscopic methods. The stoichiometric ratio in the complexes was determined by the elemental analysis method. By using FT-IR, FT-Raman and 1H and 13C NMR spectroscopy methods, it was observed that thiosemicarbazones were bound in the thione form and η1-S coordination type and µ2-Cl bridging bond in all complexes. Thermal stability and degradation steps due to heating were examined by thermogravimetric differential thermal analysis method (TG-DTA).
