TeI3[AsF6] is formed from Te, I2, and AsF5 in liquid SO2. At room temperature light red crystals of the hemi SO2 solvate TeI3[AsF6] · 0.5 SO2 are obtained from a saturated solution. The crystal structure (orthorhombic, Pnnm, a=1107.41(2), b=1866.58(3), c=1207.00(2) pm at 123 K, Z =8) consists of pyramidal TeI3+ cations (Te-I = 267 pm), almost regular octahedral [AsF6]− anions and of SO2 molecules which show disorder for the O atom positions. A remarkable feature of the crystal structure is the arrangement of the TeI3+ ions that are pairwise associated, facing each other with the I atoms and forming large voids between each other. This causes the significantly lower density of TeI3[AsF6] · 0.5 SO2 (3.88 Mgm−3) in comparison to the unsolvated form (4.20 Mgm−3, Pass more 1981).
