Iridium complex [Ph 4Sb(DMSO)] +[IrCl 4(DMSO) 2] - (1) has been synthesized by interaction of tetraphenylstibonium chloride with sodium hexachloroiridate(III) in water. From X-ray diffraction analysis data, two types of crystallographically independent cations [Ph 4Sb(DMSO)] + and anions [IrCl 4(DMSO) 2] - exist in the crystal. The antimony atoms in cations have distorted trigonal-bipyramidal surroundings with O-dimethyl sulphoxide ligand in axial position (equatorial angles CSbC 113.6(2)°-121.2(2)°, axial angles CSbО 178.33(18)°, 176.47(18)°, bond lengths Sb-С eq 2.106(6)-2.119(6) Å, Sb-С ax 2.126(6), 2.130(6) Å, Sb-О 2.545(4), 2.465(4) Å). In mononuclear octahedral anions the equatorial positions are occupied by chlorine atoms (angles ClIrCl- trans 178.69(7)°-179.56(7)°, SIrS- trans 178.35(7)°, 175.88(7)°; dimethyl sulfoxide ligands are coordinated with iridium atoms through sulfur atoms (Ir-S 2.2958(16)-2.3148(17) Å), bond lengths Ir-Cl vary in the range 2.3407(19)-2.3681(17) Å. The structural organization in the crystal is determined by interionic hydrogen bonds (H∙∙∙Cl 2.80-2.94 Å and H∙∙∙O 2.56-2.71 Å).
