Accurate Redetermination of Diiodobis(phenylsulfonyl)methane, (PhSO₂)₂CI₂

The structure of the title compound, C₁₃H₁₀I₂O₄S₂, has been redetermined, with proper treatment of both anomalous dispersion and absorption. The unusual structural features reported in an earlier determination [Stergioudis, Bozopoulos, Kavounis & Rentzeperis (1989). Z. Kristallogr. 189, 57–63] are not reproduced by the present analysis; the structure and conformation of the title compound are now found to be very similar to those of (PhSO₂)₂CBr₂; the molecules are joined into chains along the a direction by very short I...O interactions [I...O 2.927 (7) Å].
