title: 2-(4-Fluoro-phen-yl)-3-methyl-sulfinyl-5-phenyl-1-benzofuran.
abstract: In the title mol-ecule, C(21)H(15)FO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent are situated on the opposite sides of the plane through the benzofuran fragment. The benzofuran ring plane makes dihedral angles of 28.63 (6) and 31.55 (5)° with the 4-fluoro-phenyl and phenyl rings, respectively. Weak C-H⋯F and C-H⋯O hydrogen bonds and inter-molecular C-H⋯π inter-actions are present in the crystal structure. The title crystal was refined as an inversion twin with a 0.39 (7):0.61 (7) domain ratio.
