The palladium complex [Ph 3PCH=CHPPh 3] 2+[PdBr 3∙DMSO] -2∙DMSO (1) has been synthesized by the reaction of palladium dibromide with 1,2-vinylene-bis-triphenylphosphonium dibromide in the presence of hydrobromic acid in water, followed by recrystallization from dimethylsulfoxide. According to the X-ray diffraction data, the phosphorus atoms in cations have a slightly distorted tetrahedral environment (CPC 107.8(3)°-111.7(3)° Å), the P-С bond lengths are 1.779(6)-1.816(5) Å. In the square planar anions, the SPdBr trans-angles are 176.89(5)° and 178.11(6)° Å, and the BrPdBr trans-angles are 177.59(4)° and 177.82(3)° Å. Dimethylsulfoxide ligands are coordinated to the Pd atoms by the sulfur atoms: the Pd-S bond lengths are 2.2634(17) and 2.2666(18) Å, the Pd-Br bond lengths lie in the range of 2.4200(18)-2.4486(9) Å. Structural organization of the crystal is caused by the interionic H∙∙∙Br (2.90-3.02 Å) and H∙∙∙O (2.30-2.56 Å) hydrogen bonds.
