In the title compound, C18H17FO3S, the dihedral angle between the plane of the benzo-furan ring [r.m.s. deviation = 0.006 (1) Å] and that of the 4-fluoro-phenyl ring [r.m.s. deviation = 0.004 (1) Å] is 82.45 (4)°. In the crystal, mol-ecules 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 inter-actions [inter-centroid distance = 3.566 (1) Å] between the furan rings of inversion-related mol-ecules, forming a two-dimensional network lying parallel to (100).
在标题化合物C₁₈H₁₇FO₃S中，苯并呋喃环平面[r.m.s.偏差 = 0.006 (1) Å]与4-氟苯环平面[r.m.s.偏差 = 0.004 (1) Å]之间的二面角为82.45 (4)°。在晶体中，分子通过三对不同的C—H⋯O氢键相连，沿[001]方向形成链状结构，并包含两个R (2) 2(10)和一个R (2) 2(12)环单元。这些链通过反演相关分子的呋喃环之间的π-π相互作用[质心间距 = 3.566 (1) Å]进一步相连，形成一个平行于(100)的二维网络。
