Abstract: In the molecule of the title compound, C₁₆H₁₁FOS, the benzene ring is oriented at a dihedral angle of 89.68 (3)° with respect to the planar [maximum deviation 0.009 (2) Å] isocoumarin ring system. An intramolecular C-HS interaction results in the formation of a planar five-membered ring. In the crystal structure, intermolecular C-HO hydrogen bonds link the molecules into chains parallel to the c axis. A - contact between the isocoumarin rings [centroid-centroid distance = 3.818 (3) Å] may further stabilize the structure.
