title: Crystal structure of N,N-di-ethyl-benzene-1,4-diaminium dinitrate.
abstract: In the structure of the title mol-ecular salt, C10H18N2 (2+)·2NO3 (-), the dinitrate salt of 4-(N,N-di-ethyl-amino)-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.
