title: 3-Ethyl-sulfinyl-2-(3-fluoro-phen-yl)-5,6-methyl-enedi-oxy-1-benzofuran.
abstract: In the title compound, C17H13FO4S, the 3-fluoro-phenyl ring makes a dihedral angle of 6.14 (5)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯F, C-H⋯O and C-H⋯π inter-actions, forming a three--dimensional network. The crystal structure also exhibits slipped π-π inter-actions between the 3-fluoro-phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.769 (2) Å and slippage = 1.684 (2) Å].
