Crystal structure of 5-chloro-2-(2-fluorophenyl)-3-methylsulfinyl-1-benzofuran

Abstract

In the title compound, C15H10ClFO2S, the dihedral angle between the mean planes of the benzofuran ring [r.m.s. deviation = 0.007 (1) Å] and the 2-fluorophenyl ring is 32.53 (5)°. In the crystal, molecules related by inversion are paired into dimers via two different C—H...O hydrogen bonds. Further, Cl...O halogen bonds [3.114 (1) Å], and F...π [F-to-furan-centroid distance = 3.109 (1) Å] and S...F [3.1984 (9) Å] interactions link these into a three-dimensional network.
