2-[4-(Tri­fluoro­meth­yl)phenyl­sulfan­yl]benzoic acid

In the title compound, C14H9F3O2S, the dihedral angle between the mean planes of the benzene rings is 88.7 (2)°. The carb­oxy­lic acid group is twisted by 13.6 (7)° from the mean plane of its attached aromatic ring. One of the F atoms of the tri­fluoro­methyl group is disordered over two sites in a 0.61 (7):0.39 (7) ratio. In the crystal, inversion dimers linked by pairs of O—H⋯O hydrogen bonds generate R22(8) loops. Weak C—H⋯F inter­actions are also observed
