【 摘 要 】

The title salt, C8H20N22+·2NO3−, was obtained by a reaction between 1,3-cyclohexa­nebis(methyl­amine) and nitric acid. The cyclo­hexane ring of the organic cation is in a chair conformation with the methyl­ammonium substituents in the equatorial positions and the two terminal ammonium groups in a trans conformation. In the crystal, mixed cation–anion layers lying parallel to the (010) plane are formed through N—H⋯O hydrogen-bonding inter­actions; these layers are formed by infinite undulating chains running parallel to the [001] direction. The overall inter­molecular inter­actions involved in the structure were qu­anti­fied and fully described by Hirshfeld surface analysis. In addition, energy-framework calculations were used to analyse and visualize the three-dimensional topology of the crystal packing. The electrostatic energy framework is dominant over the dispersion energy framework.
