title: 3,4-Di-fluoro-2-hy-droxy-benzoic acid.
abstract: In the title compound, C7H4F2O3, an intra-molecular O-H⋯O hydrogen bond is observed. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(8) ring motifs. These dimers are linked by C-H⋯O and C-H⋯F hydrogen bonds, forming sheets lying parallel to (30-1). The sheets are linked by aromatic π-π stacking inter-actions [inter-centroid distance = 3.7817 (9) Å], forming a three-dimensional structure.
