Abstract: In the title compound, C₁₀H₈N₈·C₈H₆O₄, both acid and base molecules (A:B) have twofold crystallographic symmetry. One-dimensional zigzag chains of rings form as (AB)_n through O-HN and C-HO=C interactions; further association of B (with A) along the a axis via bifurcated N-HN and - stacking interactions gives a three-dimensional self-penetrating structure.
