摘要
In the structure of the title salt, C12H10N3O4 +center dot C7H3N2O7 -, the cations and the anions are linked by a single N+-H...O-carboxyl hydrogen bond, the discrete cation-anion unit having no intermolecular associations other than weak cation-anion aromatic ring pi-pi interactions [ring centroid separation = 3.7320 (14) A] and a number of weak inter-unit aromatic C-H...O contacts. An intramolecular C-H...O hydroxyl-carboxyl hydrogen bond occurs in the anion.
