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

Abstract

In the title compound, C36H40N5O6+·NO3−·2C2H5OH, 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.
