Abstract
In the title compound, C17H19NO3S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.080 (2) Å, and the morpholine ring adopts a chair conformation. The bond-angle sum at the N atom is 358°. The coumarin unit makes dihedral angle of 86.34 (9)° with the morpholine ring. A short intramolecular C—H...S contact generates anS(7) ring. In the crystal, inversion dimers linked by pairs of weak C—H...O hydrogen bonds generateR22(16) loops. Aromatic π–π interactions interactions [shortest centroid–centroid distance = 3.8599 (13) Å] also occur.
