Abstract
The hexane-1,6-diammonium cation of the title compound, C6H18N2 2+·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 R 4 4(26) is observed.
