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 7 H 4 ClNO 4 , the molecules form centrosymmetric dimers through OÐHÁ Á ÁO hydrogen bonds. The dimers are connected by CÐHÁ Á ÁO hydrogen bonds to form molecular tapes. Disorder of the H atom in the OÐ HÁ Á ÁO hydrogen bond is suggested.
