In the title compound, C 10 H 8 N 8 ÁC 8 H 6 O 4 , both acid and base molecules (A:B) have twofold crystallographic symmetry. One-dimensional zigzag chains of rings form as (AÁ Á ÁBÁ Á Á) n through O-HÁ Á ÁN and C-HÁ Á ÁO C interactions; further association of B (with A) along the a axis via bifurca
