title: Hexane-1,6-diammonium dinitrate.
abstract: The hexane-1,6-diammonium cation of the title compound, C(6)H(18)N(2) (2+)·2NO(3) (-), lies across a crystallographic inversion centre and shows significant deviation from planarity in the hydro-carbon 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 inter-actions to the nitrate anion. Complex hydrogen-bonded ring and chain motifs are also evident, in particular a 26-membered ring with graph-set notation R(4) (4)(26) is observed.
