Abstract
There are two crystallographically independent molecules in the asymmetric unit of the title compound, which are linked by pairwise O—H⋯O hydrogen bonds.
The title compound, C13H10FNO2, was obtained by the reaction of 2-bromo-4-fluorobenzoic acid with aniline. There are two independent molecules, A and B, in the asymmetric unit, with slight conformational differences: the dihedral angles between the aromatic rings are 55.63 (5) and 52.65 (5)°. Both molecules feature an intramolecular N—H⋯O hydrogen bond. In the crystal, the molecules are linked by pairwise O—H⋯O hydrogen bonds to form A–B acid–acid dimers and weak C—H⋯F interactions further connect the dimers.
