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 hydroge

In the title compound, C 22 H 16 ClN 3 O 3 , molecules are linked into chains along the c axis by C-HÁ Á ÁO hydrogen bonds, while other C-HÁ Á ÁN hydrogen bonds connect the chains into two-dimensional layers. The packing is further stabilized byinteractions.
