title: Crystal structure of (7-fluoro-2-oxo-2H-chromen-4-yl)methyl morpholine-4-carbodi-thio-ate.
abstract: 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 R 2 (2)(8) loops; C-H⋯O hydrogen bonds connect the dimers into [010] chains. Weak aromatic π-π stacking inter-actions between the pyran rings of the chromene systems [centroid-centroid distance = 3.6940 (16) Å] are also observed.
