In the title compound, C(19)H(13)BrO(2)S, the 4-bromo-phenyl ring makes a dihedral angle of 83.75 (4)° with the mean plane of the naphtho-furan fragment [r.m.s. deviation = 0.024 (2) Å]. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. These dimers are connected by weak π-π inter-actions between the central naphtho-furan benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.483 (2) Å, inter-planar distance = 3.416 (2) Å and slippage = 0.680 (2) Å].
在标题化合物C(19)H(13)BrO(2)S中，4-溴苯基环与萘并呋喃片段的平均平面形成83.75 (4)°的二面角[r.m.s.偏差 = 0.024 (2) Å]。在晶体中，分子通过C-H⋯O氢键对相连，形成反演二聚体。这些二聚体通过相邻分子的中心萘并呋喃苯环之间的弱π-π相互作用相连[质心-质心距离 = 3.483 (2) Å，平面间距离 = 3.416 (2) Å，滑移 = 0.680 (2) Å]。
