3-(2-Bromophenylsulfinyl)-2,5,7-trimethyl-1-benzofuran

In the title compound, C17H15BrO2S, both the benzofuran and 2-bromophenyl rings are virtually planar, with r.m.s. deviations of 0.009 (2) and 0.006 (2) angstrom, respectively. The dihedral angle between these mean planes is 89.31 (7)degrees. In the crystal, molecules are linked via pairs of C-H center dot center dot center dot pi interactions into inversion dimers. These dimers are further linked by C-H center dot center dot center dot pi interactions into supramolecular chains running along the b axis. In addition, C-S center dot center dot center dot pi interactions, with an S-to-ring-centroid distance of 3.50 (2) angstrom, are observed between inversion-related dimers.
