Abstract
In the title compound, C15H14FNO3S2, the 2H-chromene ring system is close to being planar (r.m.s. deviation = 0.024 angstrom) 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)degrees. In the crystal, inversion dimers linked by pairs of very weak C-H center dot center dot center dot F hydrogen bonds generate R-2(2)(8) loops; C-H center dot center dot center dot O hydrogen bonds connect the dimers into 010] chains. Weak aromatic pi-pi stacking interactions between the pyran rings of the chromene systems centroid-centroid distance = 3.6940 (16) angstrom] are also observed.
