title: 5-Chloro-3-(4-fluoro-phenyl-sulfon-yl)-2,7-dimethyl-1-benzo-furan.
abstract: In the title compound, C16H12ClFO3S, the dihedral angle between the plane of the benzo-furan ring system [r.m.s. deviation = 0.007 (1) Å] and that of the 4-fluoro-phenyl ring is 76.11 (5)°. In the crystal, mol-ecules are linked into [010] chains via two different inversion-generated pairs of C-H⋯O hydrogen bonds. The crystal structure also exhibits weak π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.820 (2) Å].
