3-(4-Chloro-phenyl-sulfin-yl)-2,4,7-tri-meth-yl-1-benzo-furan.

In the title compound, C17H15ClO2S, the dihedral angle between the mean plane [r.m.s. deviation = 0.020†(2)†à ] of the benzo-furan ring system and the mean plane [r.m.s. deviation = 0.011†(1)†à ] 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)†à , inter-planar distance = 3.648†(3)†à and slippage = 1.656†(3)†à ].
