title: 3-(4-Chloro-phenyl-sulfin-yl)-2,4,7-tri-meth-yl-1-benzo-furan.
abstract: In the title compound, C17H15ClO2S, the dihedral angle between the mean plane [r.m.s. deviation = 0.020 (2) Å] of the benzo-furan ring system and the mean plane [r.m.s. deviation = 0.011 (1) Å] of the 4-chloro-phenyl ring is 72.68 (6)°. In the crystal, mol-ecules are linked via pairs of C-H⋯π inter-actions into inversion dimers. These dimers are further packed by C-H⋯O hydrogen bonds into supra-molecular chains running along the a-axis direction. In addition, the crystal structure also exhibits π-π inter-actions between the 4-chloro-phenyl rings of adjacent mol-ecules [centroid-centroid distance = 4.094 (3) Å, inter-planar distance = 3.648 (3) Å and slippage = 1.656 (3) Å].
