In the title compound, C(20)H(12)FIO(2)S, the dihedral angles between the mean plane [r.m.s. deviation = 0.014 (1) Å] of the benzofuran fragment and the pendant 4-fluoro-phenyl and phenyl rings are 8.0 (1) and 86.06 (6)°, respectively. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds. The crystal structure also exhibits weak π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.547 (2) Å, inter-planar distance = 3.397 (2) Å and slippage = 1.021 (2) Å].
在标题化合物C₂₀H₁₂FIO₂S中，苯并呋喃片段的平均平面[r.m.s.偏差 = 0.014 (1) Å]与悬垂的4-氟苯基和苯基环之间的二面角分别为8.0 (1)°和86.06 (6)°。在晶体中，分子通过弱C-H⋯O氢键相连。晶体结构还在相邻分子的呋喃环和苯环之间表现出弱的π-π相互作用[质心-质心距离 = 3.547 (2) Å，平面间距离 = 3.397 (2) Å，滑移 = 1.021 (2) Å]。
