Abstract: The title compound, C₁₆H₁₃IO₂S, was prepared by the oxidation of 2-(4-iodophenyl)-5-methyl-3-methylsulfanyl-1-benzofuran with 3-chloroperoxybenzoic acid. The 4-iodophenyl ring makes a dihedral angle of 37.97 (9)° with the plane of the benzofuran fragment, and the O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of this plane. The molecular packing is stabilized by C-H interactions between H atoms on the 4-iodophenyl ring and the benzofuran rings, and by an IO halogen bond of 3.252 (2) Å with a nearly linear C-IO angle of 163.06 (8)°. In addition, the stacked molecules exhibit inversion-related SO contacts [3.209 (2) Å] involving the sulfinyl groups.
