Abstract
Tetraphenylantimony arenesulfonates were synthesized by the reaction of pentaphenylantimony with arenesulfonyl chlorides in toluene taken in a molar ratio of 1 : 1 : 2 in air. The structure of tetraphenylantimony 4-methylbenzenesulfonate was determined by X-ray diffraction analysis. The Sb atom has a distorted trigonal-bipyramidal coordination with phenyl and arenesulfonate groups in the axial positions. The Sb–C(Ph)eq bond lengths vary in the 2.099(2)–2.123(2) Å range, and the Sb–C(41) and Sb–O(1) distances are 2.136(2) and 2.499(1) Å, respectively. The O(1)SbC(4) axial angle is 175.77(5)°.
