RESUMO
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 mol-ecule 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-Hâ¯O hydrogen bonding. In addition, neighbouring cations are connected by inter-molecular N-Hâ¯O hydrogen bonds and π-π inter-actions between the benzamide groups of the cations [centroid-centroid distance = 4.000â (3)â Å], forming a chain along [001]. The ethanol solvent mol-ecules are arranged on the side of the chain through O-Hâ¯O hydrogen bonds.
