organic compounds
In the crystal structure of the title compound, C15H11FN2O2S, the torsion angle about the N—S bond between the quinoline ring system and the benzene ring is −59.0 (2)°. The sulfonamide H atom forms one intramolecular hydrogen bond to the quinoline N atom [N—HN = 2.25 (2) Å] and an intermolecular hydrogen bond to a sulfonyl O atom [N—HO =2.53 (2) Å]. The C atom adjacent to the quinoline N atom forms one intermolecular contact to the F atom [HF = 2.48 (2) Å].
