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

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