2,6-Difluorobenzoic acid
Abstract
In the title compound, C7H4F2O2, the dihedral angle between the benzene ring and the carboxylate group is 33.70 (14)°. In the crystal structure, inversion dimers linked by pairs of O—H...O hydrogren bonds occur, generating R22(8) loops. The dimers are linked into sheets lying parallel to (102) by C—H...F hydrogen bonds.
