| Summary: | In the title compound, C17H15ClO2S, 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].
