In the crystal structure of the title salt, C7H12N2 (2+)·2NO3 (-), the nitrate ions are located in the vicinity of the protonated amine groups, accepting strong N-H⋯O hydrogen bonds. Each ammonium group is involved in a total of three such inter-actions with neighbouring nitrate ions, generating a three-dimensional network. In addition, there are π-π inter-actions between the aromatic rings of centrosymmetrically related di-ammonium moieties, with a centroid-centroid distance of 3.682 (1) Å.
