In the title compound, 3C10H8N2·4C7H5NO4, the asymmetric unit contains two molecules of pyridine-3,5-dicarboxylic acid and one molecule of 4,4′-bipyridine in general positions together with one molecule of 4,4′-bipyridine lying across a centre of inversion, thus giving a 4:3 molar ratio of pyridine-3,5-dicarboxylic acid to 4,4′-bipyridine. The dihedral angle between the bipyridine rings on general positions is 21.2 (2)°. These molecular units are linked by O—H⋯N hydrogen bonds forming an extended two-dimensional framework in the crystal.
