Abstract: The title compound, C15H11IO2S, was prepared by the oxidation of 5-iodo-3-methylsulfanyl-2-phenyl-1-benzofuran using 3-chloroperbenzoic acid. The O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The phenyl ring is rotated out of the benzofuran plane, with a dihedral angle of 29.84 (6)°. The crystal structure is stabilized by normal intermolecular aromatic - stacking interactions with a centroid-to-centroid distance of 3.836 (3) Å between the furan rings of neighboring molecules, by a weak C-HO hydrogen bond, and by an IO halogen bond with an IO distance of 3.209 (2) Å and a nearly linear C-IO angle of 169.12 (6)°.
