3-(3-Fluoro-phenyl-sulfin-yl)-2,4,6-trimethyl-1-benzofuran.

In the title compound, C(17)H(15)FO(2)S, the 3-fluoro-phenyl ring makes a dihedral angle of 78.38 (4)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits a slipped π-π inter-action between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distances = 3.628 (2) Å, inter-planar distance = 3.417 (2) Å and slippage = 1.219 (2) Å].
