2-Chloro-6-fluorobenzoic acid

The title compound, C7H4ClFO2, is a twofold halogenated derivative of benzoic acid. The C—C—C angles within the aromatic moiety cover a range 116.11 (14)–123.96 (15)°, with the maximum and the minimum value next to each other. In the crystal, O—H...O hydrogen bonds form carboxylic acid dimers, which are further connected by C—H...F contacts into undulating sheets perpendicular to the a axis
