Abstract: The title compound, C9H3F5O2, crystallizes as O-HO hydrogen-bonded carboxylic acid dimers that, together with C-HF interactions and OF [2.8065 (13) and 2.9628 (13) Å] and FF [2.6665 (11), 2.7049 (12) and 2.7314 (12) Å] contacts, form a sheet-like structure. The sheets are stacked via short - interactions [centroid-centroid distance = 4.3198 (11) Å]. An intramolecular C-HF interaction is also observed.
