title: 3-(4-Fluoro-phenyl-sulfin-yl)-2,5,7-trimethyl-1-benzofuran.
abstract: In the title mol-ecule, C(17)H(15)FO(2)S, the O atom and the 4-fluoro-phenyl group of the 4-fluoro-phenyl-sulfinyl substituent lie on opposite sides of the benzofuran fragment. The mean planes of the benzofuran and 4-fluoro-phenyl fragments form a dihedral angle of 86.07 (4)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked via inter-molecular C-H⋯π inter-actions.
