Synthesis method of tetra(para-tolyl)stibonium benzenesulfonate from tetra(para-tolyl)stibonium chloride and benzenesulphonic acid

Abstract

The interaction of tetra(para-tolyl)stibonium chloride p-Tol4SbCl (1) with benzenesulfonic acid was used to synthesize tetra(para-tolyl)stibonium benzenesulfonate p-Tol4SbOSO2Ph (2). The struc-ture of compounds 1, 2 was established by X-ray diffraction analysis (XRD). According to XRD da-ta, tetra(para-tolyl)stibonium chloride p-Tol4SbCl (1) [C28H28ClSb, M = 521,70; monoclinic syngony, sp. gr. P21/n; cell parameters: a = 9.786(3) Å, b = 23.168(8) Å, c = 12.026(5) Å;  = 90.00, β = 113.689(16),  = 90.00, V = 2496.6(16) Å3, Z = 4; (calc.) = 1.388 g/cm3;  = 1.224 mm–1; F(000) = 1056.0; region 2q collection: 6.44–56.72; –13 ≤ h ≤ 13, –30 ≤ k ≤ 30, –15 ≤ l ≤ 15; total reflections 59454; independent reflections 6189 (Rint = 0.0394); GOOF = 1.055; R-factor 2.72%] has a molecular structure with a distorted trigonal-bipyramidal coordination of the antimony atom (the CSbC angles vary within 96.12(8)–124.83(8), the CSbCl axial angle is 174.91(6), the Sb–C and Sb–Cl distances are 2.107(2)–2.170(2) and 2.7230(13) Å). Tetra(para-tolyl)stibonium benzenesulfonate p-Tol4SbOSO2Ph (2) [C34H33O3SSb, M = 643,1; rhombic system, sp. gr.
