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

In the title compound, C(36)H(40)N(5)O(6) (+)·NO(3) (−)·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⋯O hydrogen bonding. In addition, neighbouring cations are connected by inter­molecular N—H⋯O hydrogen bonds and π–π inter­actions between the benzamide groups of the cations [centroid–centroid distance = 4.000 (3) Å], forming a chain along [001]. The ethanol solvent mol­ecules are arranged on the side of the chain through O—H⋯O hydrogen bonds.
