Tetra-p-tolylantimony 4-methylbenzenesulfonate (I) was synthesized via the reaction of tri-p-tolyl-bismuth bis(4-methylbenzenesulfonate) with penta-p-tolylantimony in toluene. According to the X-ray diffraction data, the antimony atoms of two individual molecules of I have a distorted trigonal bipyramidal coordination with the axial 4-methylbenzenesulfonate ligand and three equatorial tolyl ligands, one of which contains four carbon atoms disordered over two sites with the occupancy factors 0.7 and 0.3.
