Abstract: There are two symmetry-independent molecules in the asymmetric unit of the title compound, C₁₃H₁₃IO₄S. In each molecule, the O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic - interactions between the benzene and furan ring [centroid-centroid distance = 3.866 (7) Å], and by intermolecular C-H interactions and a sulfinyl-sulfinyl interaction [SO = 3.025 (4) Å]. The crystal structure also exhibits weak intermolecular C-HO hydrogen bonds and two different IO halogen bonds.
