3-Ethyl-sulfinyl-5-fluoro-2-(4-iodo-phen-yl)-1-benzofuran.

In the title compound, C(16)H(12)FIO(2)S, the 4-iodo-phenyl ring is rotated slightly out of the benzofuran plane, as indicated by the dihedral angle of 11.41 (7)°. The crystal structure is stabilized by an inter-molecular π-π inter-action between the benzene and 4-iodo-phenyl rings [centroid-centroid distance = 3.757 (3) Å]. The crystal structure also exhibits a weak inter-molecular C-H⋯O hydrogen bond and a short I⋯O [3.2575 (16) Å] contact.
