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.

All H atoms were positioned geometrically, with C—H = 0.93 Å for aromatic H, C—H = 0.97 Å for methylene H and C—H = 0.96 Å for methyl H,and refined using a riding model with Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C) for all other H.
Coumarin derivatives have many uses as antibiotics, antiviral, antimicrobial and anticoagulants agents and as pH indicators in biological systems and medical sciences (Starčević et al., 2011; Lodeiro et al., 2010; Danko et al.,2011).
The π–π interactions between pyran rings of chromene (C11—C16) [shortest centroid–centroid distance = 3.6940 (16) Å] are observed (Figure 2).

The 2H-chromene ring systems (O4/C8–C16) is nearly planar, with a maximum deviation of 0.0591 (30) Å for atoms C8 and the morpholine ring adopts a chair conformation. The dihedral angle between best plane through the 2H-chromene(O4/C8–C16) ring system and the morpholine (N7\O6\C19–C22) ring is 88.21 (11)°.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

Coumarin derivatives have many uses as antibiotics, antiviral, antimicrobial and anticoagulants agents and as pH indicators in biological systems and medical sciences (Starčević et al., 2011; Lodeiro et al., 2010; Danko et al.,2011).
The asymmetric unit of (7-fluoro-2-oxo-2H-chromen-4-yl)methyl morpholine-4-carbodithioate is shown in Fig. 1. The 2H-chromene ring systems (O4/C8–C16) is nearly planar, with a maximum deviation of 0.0591 (30) Å for atoms C8 and the morpholine ring adopts a chair conformation. The dihedral angle between best plane through the 2H-chromene(O4/C8–C16) ring system and the morpholine (N7\O6\C19–C22) ring is 88.21 (11)°. In the crystal, inversion-related C14—H14···F1 hydrogen bonds, forming inversion dimers with an R2 2(8) ring motif. In the crystal, weak C—H···O hydrogen bonds (Table 1) with π–π interactions between pyran rings of chromene (C11—C16) [shortest centroid–centroid distance = 3.6940 (16) Å] are observed (Figure 2).
