Crystal structures of hydrogen-bonded 1:2 dihydrate compounds of chloranilic acid with 2-carboxypyridine (I) and 2-carboxyquinoline (II) have been determined at 180 and 200 K, respectively. The base molecule in (I) is disordered over cationic and twitterionic states, while that in (II) is in a twitterionic form. In each crystal, the three components are linked by O—H⋯O and N—H⋯O hydrogen bonds, forming a layer structure.
