Abstract
The title compound, C7H8N2O4, crystallizes as a zwitterion, with molecules organized into molecular sheets via carboxyl– carboxylate and N+—H_ _ _carboxylate contacts. These sheets are constructed from translationally related molecules that further link to neighboring motifs via _-stacking [centroid– centroid distance 3.504 (3) A ° ] and weak C—H_ _ _O contacts.
