2-Fluoro-4-(methoxycarbonyl)benzoic acid

Abstract

In the crystal of the title compound, C9H7FO4, classical carboxylate inversion dimers are linked by pairs of O—H...O hydrogen bonds. The packing is consolidated by C—H...F and C—H...O interactions. The benzene ring and the methoxycarbonyl group are nearly coplanar, with a dihedral angle of 1.5 (3)° between them, whereas the carboxyl group has a dihedral angle of 20.2 (4)° with respect to the benzene ring.
