%X In the structure of the title salt, C12H10N3O4+¡¤C7H3N2O7 , the cations and the anions are linked by a single N+¡ªH...Ocarboxyl hydrogen bond, the discrete cation¨Canion unit having no intermolecular associations other than weak cation¨Canion aromatic ring ¦Ð¨C¦Ð interactions [ring centroid separation = 3.7320 (14)  ] and a number of weak inter-unit aromatic C¡ªH...O contacts. An intramolecular C¡ªH...O hydroxyl¨Ccarboxyl hydrogen bond occurs in the anion.
