Abstract
The interaction of hexachloroplatinic acid with tetraorganylphosphonium, tetraethylammonium chlorides in solutions of acetonitrile in the presence of diethylsulphoxide (deso) synthesized the following complexes: [Et 4 N][PtCl 5 (deso-S)] ( 3 ). The structures 1 3 were determined by XRDA and IR. The X-ray diffraction patterns of crystals 1 3 were obtained at 293 K on an automatic diffractometer D8 Quest Broker (MoK α radiation, λ = 0.71073 Å, graphite monochromator) the phosphorus and nitrogen atoms of complexes 1 3 have a distorted tetrahedral configuration in the cations. [C 52 H 46 N 2 Cl 6 P 2 Pt]( 1 ), M 1168.64; the triclinic syngony, the symmetry group P 1 ; cell parame-ters: a = 10.200(10), b = 10.960(15), c = 12.160(11) Å; = 73.65(4) degrees, β = 80.64(3) de-grees, = 77.48(4) degrees; V = 1266(2) Å 3 ; the crystal size GOOF 0.999; R 1 = 0.0447; wR 2 = 0.0648; residual electron density 1,60/ 1,26 e/Å 3 ]. The СРС and CNC valence angles are 107.9(3) 113.2(3) for 1 , 108.7(2) 111.2(3) for 2 , 108.6(2) 111.2(2) for 3 , distance P С 1.785(6) 1.805(6) Å in 1 ; 1.789(4) 1.801(5) Å in 2 , and distance N C 1.515(4) 1.524(4) Å in 3 . In octahedral anions [PtCl 6 ] 2− trans-angles ClPtCl equal 180.0º, distance 2.308(2)–2.327(3) Å in a crystal solvate. In the [PtCl 5 (dmso-S)] − anions of complexes 2 , 3 the SPtCl trans-angles are 175.12(5) 176.23(3) , the СlPtCl trans-angles equal 177.12(3) 178.45(3) , the distances Pt Cl and Pt S are 2.3156(14) 2.3379(14) and
