Abstract: In the title compound, C₇H₆FNO₂, the molecule is almost planar (r.m.s. deviation for the non-H atoms = 0.015 Å) and an intramolecular N-HO hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O-HO hydrogen bonds generate R₂²(8) loops. Weak N-HF hydrogen bonds, short FF contacts [2.763 (2) Å] and aromatic - stacking interactions [centroid-centroid separation = 3.5570 (11) Å] are also observed in the crystal structure.
