Abstract: In the title compound, C7H4F2O3, an intramolecular O-HO hydrogen bond is observed. In the crystal, inversion dimers linked by pairs of O-HO hydrogen bonds generate R22(8) ring motifs. These dimers are linked by C-HO and C-HF hydrogen bonds, forming sheets lying parallel to (30-1). The sheets are linked by aromatic - stacking interactions [inter-centroid distance = 3.7817 (9) Å], forming a three-dimensional structure.
