SYNTHESIS AND STRUCTURE OF TRI(META-TOLYL)ANTIMONY BIS(BENZENESULFONATE)
Tri( <i>meta</i>-tolyl)antimony <i>bis</i>(benzenesulfonate) <i>m</i>-Tol <sub>3</sub>Sb(OSO <sub>2</sub>C <sub>6</sub>H <sub>5</sub>) <sub>2</sub> (1) has been synthesized by interaction of tri( <i>meta</i>-tolyl)antimony with benzenesulfonic acid in the presence of <i>tert</i>-butyl hydroperoxide (mole ratio 1:2:1) in ether solution. Antimony atoms in 1 have trigonal-bipyramidal coordination with arenesulfonate substituents in axial positions (OSbO 171.05(11)°, CSbC 116.21(19)°, 117.38(18)°, 126.40(15)°). The Sb-C and Sb-O distances equal 2.091(4), 2.098(4), 2.115(4) and 2.105(2), 2.116(3) Å. Intermolecular contact (Sb•••O 3.421(3) Å) occurs between the central atom and the oxygen atom of sulfonate group.
