Zwitterionic 4-carboxy-2-(1-methylpyridin-1-ium-4-yl)-1H-imidazole-5-carboxylate
In the title zwitterionic molecule, C11H9N3O4, the imidazole and pyridine rings form a dihedral angle of 2.60 (2)°. An intramolecular O—H...O hydrogen bond occurs. In the crystal, pairs of N—H...O hydrogen bonds link the molecules into inversion...
