5-Chloro-3-ethyl­sulfinyl-7-methyl-2-(4-methyl­phen­yl)-1-benzo­furan

In the title compound, C(18)H(17)ClO(2)S, the dihedral angle between the mean planes of the benzo­furan ring system and the methyl­phenyl ring is 14.50 (4)°. The centroid–centroid distances between the benzene and the methyl­phenyl rings are 3.827 (2) and 3.741 (2) Å, while the centroid–centroid distance between the furan and methyl­phenyl rings is 3.843 (2) Å. These distances indicate π–π inter­actions; on the other hand, the inter­planar angles between the benzene and methyl­phenyl rings, and between the furan and methyl­phenyl rings are 13.89 (4) and 15.53 (4)°, respectively. In the crystal, the mol­ecules stack along the a-axis direction.
