2-(4-Fluoro-phen-yl)-5-iodo-7-methyl-3-methyl-sulfinyl-1-benzofuran.

In the title compound, C(16)H(12)FIO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The 4-fluoro-phenyl 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 mol-ecules into centrosymmetric dimers. These dimers are further linked via aromatic π-π inter-actions between the benzene and the 4-fluoro-phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.617 (3) Å].
