✦ Synopsis

In the crystal structure of the title 1:2 cocrystal, C~10~H~8~N~2~·2C~7~H~4~ClNO~4~, the two components are held together by short O—H...N hydrogen bonds. The pyridine rings of the bipyridyl molecule are twisted by 27.90 (5)° with respect to each other. The 1:2 units are connected by C—H...O hydrogen bonds, forming a centrosymmetric supramolecular ring.
