Crystal structure of N,N-di­ethyl­benzene-1,4-diaminium dinitrate

In the structure of the title mol­ecular salt, C(10)H(18)N(2) (2+)·2NO(3) (−), the dinitrate salt of 4-(N,N-di­ethyl­amino)­aniline, the two ethyl groups lie almost perpendicular to the plane of the benzene ring [the ring-to-ethyl C—C—N—C torsion angles are −59.5 (2) and 67.5 (3)°]. The aminium groups of the cation form inter-species N—H⋯O hydrogen bonds with the nitro O-atom acceptors of both anions, giving rise to chain substructures lying along c. The chains are linked via further N—H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to (010). These sheets are linked by C—H⋯O hydrogen bonds, forming a three-dimensional structure.
