In the title compound, C20H16O3S, the dihedral angle between the mean planes of the naphtho-furan and 3-methyl-phenyl fragments is 88.56 (2)°. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. These dimers are linked by π-π inter-actions between the furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.701 (2) Å] into supra-molecular chains running along the a-axis direction.
在标题化合物C₂₀H₁₆O₃S中，萘并呋喃和3-甲基苯基片段平均平面之间的二面角为88.56 (2)°。在晶体中，分子通过成对的C-H⋯O氢键相连，形成反演二聚体。这些二聚体通过相邻分子呋喃环之间的π-π相互作用[质心-质心距离 = 3.701 (2) Å]连接成沿a轴方向延伸的超分子链。
