The title compound, C12H18N82+·2NO3-·2H2O, was synthesized unexpectedly from 3-amino-1-methyl-1,4,5,6-tetrahydropyrrolo[3,4-c]pyrazol-5-ium chloride and cerium(IV) ammonium nitrate. The cation has a crystallographically imposed centre of symmetry. In the crystal, the ions and water molecules are linked via O-HN, N-HO and O-HO hydrogen bonds into a three-dimensional network.
