Structure cristalline de l'hexachlorotellurate(IV) d'hydroxydiméthylsoufrediméthylsulfoxyde (12) [(CH3)2SOH]2(TeCl6)· 2(CH3)2SO

(CH₃)₂SOH]₂(TeCl₆)·2(CH₃)₂SO crystallizes in the triclinic system, space group P$\text{1}$, with a 9.474(5), b 7.952(4), c 10.180(3) Å, α 109.20(3)°, β 95.75(5)° and γ 117.60(4)°, Z = 1. The structure has been determined by a single-crystal X-ray study and refined by full-matrix least squares analysis to R = 0.044 for 1332 independent reflections. The hydrogen atoms of the methyl groups were not located. The structure contains TeCl₆^2? and (CH₃)₂SOH⁺ ions and (CH₃)₂SO molecules which form layers situated along (011) planes. The TeCl₆^2? ion adopts an almost regular octahedron. The (CH₃)₂SOH⁺ cation and the (CH₃)₂SO molecule are linked by a short hydrogen bond. Interatomic distances are in good agreement with previously published values. Cohesion of the structure is due to ionic interactions, hydrogen bonds and Van der Waals interactions.
