Tri(meta-tolyl)antimony chloro(benzenesulfonate): synthesis and structure

Abstract

Tri(meta-tolyl)antimony chloro(benzenesulfonate) (I) has been synthesized by the reaction between tri(meta-tolyl)antimony bis(benzenesulfonate) and tri(meta-tolyl)antimony dichloride (toluene; 0.5 h, 100°C). According to X-ray diffraction data, the antimony atoms in two crystallographically independent molecules Ia and Ib have a distorted trigonal bipyramidal coordination to chlorine and oxygen atoms in axial positions: OSbCl, 177.8(4)° (Ia), 178.6(4)° (Ib); CSbC, 114.0(9)°‒127.6(8)° (Ia), CSbC, 114.4(8)°‒128.0(8)° (Ib); Sb‒C, 2.01(2)‒2.139(18) Å, Sb‒Cl, 2.453(7) Å, Sb‒O, 2.163(13) Å (Ia), Sb‒C, 2.07(2)‒2.14(2) Å, Sb‒Cl, 2.442(7) Å; Sb‒O, 2.187(14) Å (Ib).
