摘要：
In the title salt, C2H8N+center dot C10H6N3O5-, the imidazolecarboxylate anion is essentially planar [maximum deviation from the least-squares plane = 0.046 (5) angstrom], with a dihedral angle between the rings of 2.7 (2)degrees. This conformation is maintained by the presence of both intramolecular carboxy-carboxylate O-H center dot center dot center dot O and imidazole-oxide N-H center dot center dot center dot O hydrogen bonds. Iin the crystal, cation-carboxylate N-H center dot center dot center dot O and cationimidazole N-H center dot center dot center dot N hydrogen bonds result in chains along the b axis.
