In the title compound, C(20)H(16)O(2)S, the 4-methyl-phenyl ring makes a dihedral angle of 82.60 (4)° with the mean plane [r.m.s. deviation = 0.007 (1) Å] of the naphtho-furan fragment. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, and by a slipped π-π inter-action between the central naphtho-furan benzene rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.671 (2) Å, inter-planar distance = 3.349 (2) Å and slippage = 1.503 (2)°].
在标题化合物C₂₀H₁₆O₂S中，4-甲基苯基环与萘并呋喃片段的平均平面[r.m.s.偏差 = 0.007 (1) Å]形成82.60 (4)°的二面角。在晶体中，分子通过弱分子间C-H⋯O氢键以及相邻分子的中心萘并呋喃苯环之间的滑移π-π相互作用相连[质心到质心距离 = 3.671 (2) Å，平面间距离 = 3.349 (2) Å，滑移 = 1.503 (2)°]。
