Crystal structure of 2-ethyl-3-(4-fluoro­phenyl­sulfon­yl)-5,7-dimethyl-1-benzo­furan

In the title compound, C(18)H(17)FO(3)S, the dihedral angle between the plane of the benzo­furan ring [r.m.s. deviation = 0.006 (1) Å] and that of the 4-fluoro­phenyl ring [r.m.s. deviation = 0.004 (1) Å] is 82.45 (4)°. In the crystal, mol­ecules are linked via three different pairs of C—H⋯O hydrogen bonds, forming chains along [001] and enclosing two R (2) (2)(10) and one R (2) (2)(12) ring motifs. The chains are further linked by π–π inter­actions [inter-centroid distance = 3.566 (1) Å] between the furan rings of inversion-related mol­ecules, forming a two-dimensional network lying parallel to (100).
