3-(4-Chloro­phenyl­sulfin­yl)-2,4,7-tri­meth­yl-1-benzo­furan

In the title compound, C(17)H(15)ClO(2)S, the dihedral angle between the mean plane [r.m.s. deviation = 0.020 (2) Å] of the benzo­furan ring system and the mean plane [r.m.s. deviation = 0.011 (1) Å] of the 4-chloro­phenyl ring is 72.68 (6)°. In the crystal, mol­ecules are linked via pairs of C—H⋯π inter­actions into inversion dimers. These dimers are further packed by C—H⋯O hydrogen bonds into supra­molecular chains running along the a-axis direction. In addition, the crystal structure also exhibits π–π inter­actions between the 4-chloro­phenyl rings of adjacent mol­ecules [centroid–centroid distance = 4.094 (3) Å, inter­planar distance = 3.648 (3) Å and slippage = 1.656 (3) Å].
