Abstract
In the title organic salt, C5H7N2 +·C8H5O4 −, the carboxylic group is nearly coplanar with the benzene ring [dihedral angle 1.9 (4)°] whereas the carboxylate group is twisted relative to the benzene ring by 13.6 (4)°. In the crystal, N-H⋯O and O—H⋯O hydrogen bonds connect the components into a three-dimensional framework consisting of stacks of alternating pairs of anions and cations exhibiting π–π stacking interactions with centroid–centroid distances in the range 3.676 (2)–3.711 (1) Å. The π–π stacks extend along [110] and [-110].
