摘要：

The complex [p-(Tol)(4)Sb(DMSO-O) (2) (+) [trans-RhBr4(DMSO-S)2]-[cis-RhBr4(DMSO-S)(2)](-) (CIF file CCDC no. 1415243) was synthesized by the reaction of sodium hexabromorhodate with tetra(para-tolyl) stibonium bromide in DMSO and studied by X-ray diffraction. The antimony atoms in two types of crystallographically independent [p-Tol(4)Sb(DMSO-O)](+) cations have a distorted trigonal-bipyramidal coordination with axially arranged DMSO oxygen atoms (Sb-C, 2.088(9)-2.135(10) ; Sba (TM) a (TM) a (TM) O, 2.641(10), 2.690(10) ). In the octahedral [trans-RhBr4(DMSO-S)(2)](-) and [cis-RhBr4(DMSO-S)(2)](-) anions, the dimethyl sulfoxide ligands are coordinated to the metal via the sulfur atoms. The Rh-S distances are longer in the trans-isomer (2.333(2), 2.339(2) ) than in the cis-isomer (2.303(3), 2.318(4) ).
