ABSTRACT The asymmetric unit of the title compound, C(13)H(10)FN(3)OS(2), contains two independent mol-ecules, which differ slightly in the relative orientations of the triazole and ethyl-sulfanyl groups with respect to the planar thio-chromen-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, inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules 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.
