Experimental

R factor = 0.026; wR factor = 0.065; data-to-parameter ratio = 19.9. In the title compound, C16H12FIO2S, the 3-fluorophenyl ring makes a dihedral angle of 76.47 (6) with the mean plane [r.m.s. deviation = 0.013 (2) Å] of the benzofuran fragment. In the crystal, molecules are linked by weak C—H O hydrogen bonds,forming chains along the b-axis direction, and an I O contact [3.204 (2) Å]. The crystal structure also exhibits slipped – interactions between the 3-fluorophenyl rings of neighbouring molecules [centroid–centroid distance = 3.683 (3) A ̊ and slippage = 1.708 (3) Å].
