Abstract: Five new 4-aroylhydrazino-4-thioxo-3-thiabutyrate ligands, synthesized by the reaction of 4- aroylhydrazinodithiocarbamate and chloroacetic ester, and their complexes with tin(IV) have been prepared and characterized by elemental analyses, IR, 1H NMR spectra and molar conductance. It is shown that the O, N, and S atoms of the ligand coordinate to tin to form a chelating dimer and these ligands are tridentate and coordinate to tin(IV) in the enol form in the mole ratio 1 : 1. The central tin atom appears to be six-coordinated.
