Crystal structure of 5-chloro-2,7-dimethyl-3-[(4-methyl­phenyl)­sulfon­yl]-1-benzo­furan

In the title compound, C17H15ClO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.008 Å] and the 4-methyl-phenyl ring is 77.29 (4)°. In the crystal, mol-ecules are linked by π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.847 (2) Å] and between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.743 (2) Å]. The mol-ecules are stacked along the a-axis direction. In addition, pairs of C-H⋯O hydrogen bonds are observed between inversion-related dimers: these generate R 2 (2)(12) loops.
