Bis(2-{2-[2-(benzylcarbamoyl)phenoxy]acetamido}ethyl)ammonium nitrate ethanol disolvate

In the title compound, C(36)H(40)N(5)O(6)(+)center dot NO(3)(-)center dot 2C(2)H(5)OH, the nitrate anion is disordered over the two orientations of equal occupancy while the solvent molecule reveals large displacement parameters. The cation is formed by protonation of the N atom of a secondary amine in the middle of the flexible chain and the whole compound has crystallographically imposed C-2 symmetry with the crystallographic b axis. An O atom of the nitrate anion links the acidic H atoms of the cation via N-H center dot center dot center dot O hydrogen bonding. In addition, neighbouring cations are connected by intermolecular N-H center dot center dot center dot O hydrogen bonds and pi-pi interactions between the benzamide groups of the cations [centroid-centroid distance = 4.000 (3) angstrom], forming a chain along [001]. The ethanol solvent molecules are arranged on the side of the chain through O-H center dot center dot center dot O hydrogen bonds.
