Formatted abstract
The asymmetric unit of the title compound, C9H8NO+·C6H3N2O4·2H2O, contains two independent cations, two anions and four water mol­ecules of solvation. A three-dimensional framework structure is formed through extensive hydrogen-bonding involving most donor and acceptor species. Significant aromatic C—H⋯O and cation–cation π–π inter­actions are also present.
