Abstract: In the crystal structure of the title salt, C10H16NO2+·C7H3N2O6-, the cations adopt a dimer structure, through a head-to-tail hydrogen-bond between the dimethoxy and the ammonium groups. The cations are further connected to the anions by N-HO hydrogen bonds, forming a three-dimensional network.
