Abstract
In the title compound, C16H12FIO2S, the O atom and the methyl group of the methylsulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The 4-fluorophenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 7.43 (6)°. In the crystal structure, pairs of short I⋯O [3.074 (2) Å] contacts link the molecules into centrosymmetric dimers. These dimers are further linked via aromatic π–π interactions between the benzene and the 4-fluorophenyl rings of neighbouring molecules [centroid–centroid distance = 3.617 (3) Å].
