In the title compound, C18H26N2O22+.2NO(3)(-), both N atoms of the cat
ionic moiety are protonated and linked to two NO3- anions by intermole
cular hydrogen bonding. Intramolecular hydrogen bonding also exists be
tween the amine H and phenol O atoms. The compound displays a centrosy
mmetric structure with the two aromatic rings parallel to each other.
