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-H...O hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H...O hydrogen bonds generate R22(8) loops. Weak N-H...F hydrogen bonds, short F...F contacts [2.763 (2) Å] and aromatic [pi]-[pi] stacking interactions [centroid-centroid separation = 3.5570 (11) Å] are also observed in the crystal structure.
