- Compounds with the composition SbCl₄⁺[Sb₂F₁₁₋ₛClₛ]⁻ with 0 ≤ s ≤ 2 can be obtained from SbF₅/SbCl₅ mixtures. The title compound is one of them. Its crystal structure was determined with X-ray diffraction data and was refined to a residual index of R = 0.052. It is isotypic to the compounds with s = 0 and s = 2, crystallizing in the space group P2₁/n with a = 1103, b = 1055, c = 1290 and β = 95,9°. In the anion [F₄(F₁₋ᵤClᵤ)Sb-F-Sb(F₁₋ᵥClᵥ)F₄]⁻ two ligand positions that are cis to the bridging F atom are statistically occupied by fluorine and chlorine, with u = 0,1 and v = 0,4. The tetrahedral SbCl₄⁺ ion is coordinated to the anion so that on top of each of the tetrahedron faces there is one F atom at a distance of 298 to 335 pm.
