Abstract
The interaction of bismuth (III) iodide with tetraphenylphosphonium iodide in dimethylsulfoxide and diethylsolfoxide have synthesized bismuth complexes [Ph4P]+2[Bi2I8(m2-Et2SO-O)]2– (1) и [Ph4P]+2trans-[Bi2I8(dmso-O)2]2- (2). They have been structurally characterized. The X-ray diffraction pattern has been obtained at 293 K on an automatic diffractometer D8 Quest Bruker (MoKα-radiation, λ = 0.71073 Å, graphite monochromator) of crystals 1 [C26H24O0.5SI4BiP, M 1124.06, the monoclinic syngony, the symmetry group С2/с; cell parameters: а = 27.563(15) Å, b = 9.140(7) Å, с =28.978(17) Å; α = 90.00 degrees, β =119.069(17) degrees, γ = 90.00 degrees; V = 6381(7) Å3; the crystal size 0.43×0.35×0.19 mm; intervals of reflection indexes are –41 ≤ h ≤ 41, –13 ≤ k ≤ 13, –43 ≤ l ≤ 42; total reflections 124163; independent reflections 11658; Rint 0.0708; GOOF 1.025; R1 = 0.0852, wR2 = 0.1380; residual electron density –3.19/2.61 e/Å3][C28H32O2PS2BiI4, M 1212.21; the triclinic syngony, the symmetry group Р-1; cell parameters: а = 9.409(10) Å, b = 14.149(16) Å, с =15.745(15) Å; α = 113.85 degrees, β =92.50(4) degrees, γ = 104.05 degrees; V = 1836(3) Å3; the crystal size 0.64×0.43×0.4 mm; intervals of reflection indexes are –15 ≤ h ≤ 15, –23 ≤ k ≤ 24, –25 ≤ l ≤ 26; total reflections 117427; independent reflections 18300; Rint 0.0927; GOOF 1.006; R1 = 0.1366, wR2 = 0.1369; residual electron density –2.99/2.59 e/Å3] the phosphor atoms have a distorted tetrahedral coordination (the CPC angles are 107.7(3)–112.8(4)° (1), 107.2(3)–111.2(3)° (2); the Р–С bond lengths are 1.771(7)–1.823(8) Å (1), 1.786(6)–1.804(5) Å (2)).
