【 摘 要 】

In the title compound, C15H14FNO3S2, the 2H-chromene ring system is close to being planar (r.m.s. deviation = 0.024 Å) and the morpholine ring adopts a chair conformation. The dihedral angle between the 2H-chromene ring system and the morpholine ring (all atoms) is 88.21 (11)°. In the crystal, inversion dimers linked by pairs of very weak C—H⋯F hydrogen bonds generate R22(8) loops; C—H⋯O hydrogen bonds connect the dimers into [010] chains. Weak aromatic π–π stacking inter­actions between the pyran rings of the chromene systems [centroid–centroid distance = 3.6940 (16) Å] are also observed.
