Hexane-1,6-diammonium dinitrate

C. van Blerk and G. J. Kruger

Abstract: The hexane-1,6-diammonium cation of the title compound, C₆H₁₈N₂²⁺·2NO₃^-, lies across a crystallographic inversion centre and shows significant deviation from planarity in the hydrocarbon chain. This is evident from the torsion angle of -64.0°(2) along the N-C-C-C bond and thse torsion angle of -67.1°(2) along the C-C-C-C bonds. An intricate three-dimensional hydrogen-bonding network exists in the crystal structure, with each H atom on the ammonium group exhibiting bifurcated interactions to the nitrate anion. Complex hydrogen-bonded ring and chain motifs are also evident, in particular a 26-membered ring with graph-set notation R₄⁴(26) is observed.
