2-Ethyl­sulfanyl-7-fluoro-3-(1H-1,2,4-triazol-1-yl)-4H-thio­chromen-4-one

The asymmetric unit of the title compound, C(13)H(10)FN(3)OS(2), contains two independent mol­ecules, which differ slightly in the relative orientations of the triazole and ethyl­sulfanyl groups with respect to the planar thio­chromen-4-one frameworks. The dihedral angles between the mean planes of the triazole groups and the corresponding six-membered C(5)OS rings are 56.8 (1) and 52.9 (1)°, while the S—C—S—C dihedral angles are −11.7 (2) and −16.3 (2)°. In the crystal structure, inter­molecular C—H⋯O and C—H⋯N hydrogen bonds link the mol­ecules in a stacked arrangement along the a axis. A weak intramolecular C—H⋯·O interaction results in the formation of a non-planar five-membered ring.
