The crystal structure of the title compound, hexatellurium tetrakis(hexafluoroarsenate) sulfur dioxide disolvate, Te6[AsF6]4·2SO2, was first determined by Burns, Gillespie, Luk & Slim [Inorg. Chem. (1979), 18, 3086-3094]. We present here a redetermination at low temperature and of improved precision, in which all atoms were refined with anisotropic displacement parameters.

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
