2,13-Dibenzyl-5,16-diethyl-2,6,13,17-tetraazatricyclo[16.4.0.07,12]docosan-2-ium nitrate

One of the tertiary amine atoms has been protonated in the title salt, C36H57N4+·NO3−. The four N atoms of the macrocycle are almost coplanar (r.m.s. deviation = 0.0053 Å), a result correlated with the formation of intramolecular N—H...N and N—H...(N,N) hydrogen bonds. With respect to this plane, the benzyl groups lie to either side; a similar arrangement pertains for the cyclohexyl rings (each with a chair conformation). Helical supramolecular chains are evident in the crystal, whereby alternating cations and anions are linked by C—H...O interactions. The chains are consolidated into supramolecular arrays in the ab plane via C—H...π contacts involving both benzene rings.
