In the title compound, C(19)H(17)NO(3)S(2), the morpholine ring is in a chair conformation. In the coumarin ring system, the dihedral angle between the benzene and pyran rings is 3.9 (1)°. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into corrugated layers parallel to (102). The crystal packing also exhibits π-π inter-actions, with distances of 3.644 (1) and 3.677 (1) Å between the centroids of the benzene rings of neighbouring mol-ecules.
在标题化合物C(19)H(17)NO(3)S(2)中,吗啉环呈椅式构象。在香豆素环系中,苯环和吡喃环之间的二面角为3.9 (1)°。在晶体中,弱的C-H⋯O相互作用将分子连接成平行于(102)的波纹层。晶体堆积还表现出π-π相互作用,相邻分子苯环中心之间的距离为3.644 (1) 和3.677 (1) Å。
