A 1:1 cocrystal of 2,8-bis­­(tri­fluoro­methyl)quinolin-4-ol and 2,8-bis­­(tri­fluoro­meth­yl)quinolin-4(1H)-one

In the title compound, C11H5F6NO·C11H5F6NO, 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
