✦ Synopsis

In the title compound, C~11~H~5~F~6~NO·C~11~H~5~F~6~NO, both molecules (except F and H atoms) are essentially planar (the r.m.s. deviations for all non-H atoms are 0.008 and 0.034 Å for the alcohol and ketone, respectively). The two molecules are connected by an O—H...O hydrogen bond. The protonated N atom is shielded and therefore does not form a hydrogen bond. The F atoms of one trifluoromethyl group are disordered over two positions; the site occupancy factors are 0.88 and 0.12.
