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.

Pentaarylantimony Ar3Sb (Ar = Ph, p-Tol) arylates diarylbismuth arylsulfonates Ar2BiOSO2Ar' (Ar' = C6H4Me-4; C6H3Me2-2,4, C6H3Me2-2,5) in ether at 20 degreesC (48 h) to form triarylbismuth in yields of up to 95%. The second reaction product is tetraarylantimony arenesulfonate. The reaction of pentaphenylantimony with phenylbismuth bis(arenesulfonate) PhBi(OSO2Ar')(2) under the same conditions leads to formation of diphenylbismuth arenesulfonate and tetraphenylantimony arenesulfonate in yields of up to 90%.
