2,13-Dibenzyl-5,16-diethyl-2,6,13,17-tetra­aza­tricyclo­[16.4.0.0(7,12)]docosan-2-ium nitrate

One of the tertiary amine atoms has been protonated in the title salt, C(36)H(57)N(4) (+)·NO(3) (−). 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.
