5-Bromo-3-(4-fluoro-phenyl-sulfon-yl)-2,7-dimethyl-1-benzofuran.

In the title compound, C(16)H(12)BrFO(3)S, the 4-fluoro-phenyl ring makes a dihedral angle of 72.35 (5)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. 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 slipped π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.667 (2) Å and slippage = 1.341 (2) Å], and between the benzene and the furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.759 (2) Å and slippage = 0.757 (2) Å].
