Abstract
Abstract The reaction of Se, I2 and WCl6 in the molar ratio 12:1:2 in a sealed evacuated ampoule at 423 K yields (Se6I+)n · n(WCl6 −) in quantitative yield as black, moisture sensitive crystals with a bronze luster. The compound crystallizes triclinic (space group P[unk]) with the lattice constants a = 670.1(3) pm, b = 741.7(5) pm, c = 803.5(5)pm, α = 92.18(5)°, β = 97.71(4)°, γ = 95.48(4)°. The structure was refined to RW (F 2) = 9.2% based on 2248 unique reflections and r(|F|) = 3.7% based on 1912 reflections with |F| > 4σ(F). The one-dimensional polymeric cation (Se6I+) n is built of Se6 rings in the chair conformation which are connected by iodine atoms bound to the Se6 rings in the 1,4 positions and forming linear bridges. The WCl6 − anions form slightly distorted octahedra. The structure is compared with that of (Se6I)MF6 (M = As, Sb) with a nearly isostructural polycation.
