2-Methylbenzene-1,3-diammonium dinitrate

Abstract

In the crystal structure of the title salt, C7H12N22+·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 interactions with neighbouring nitrate ions, generating a three-dimensional network. In addition, there are π–π interactions between the aromatic rings of centrosymmetrically related diammonium moieties, with a centroid–centroid distance of 3.682 (1) Å.
