Abstract

The asymmetric unit of the title compound, C9H8NO+烶H3N2O4-粈2O, 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 [pi]-[pi] interactions are also present.The asymmetric unit of the title compound, C9H8NO+烶H3N2O4-粈2O, contains two independent cations, two anions and four water molecules of solvation.
