Abstract

The mol­ecule of the title ethanol solvate, C₁₅H₂₁N₃O₆·C₂H₆O, adopts a curved shape; the conformation about the imine bond [N=N = 1.287 (3) Å] is E. The amide residues occupy positions almost orthogonal to each other [dihedral angle = 85.7 (2)°]. In the crystal, a network of O-HO, O-HN and N-HO hydrogen bonds leads to the formation of supra­molecular arrays in the ab plane with the ethanol mol­ecules lying to the periphery on either side. Disorder in the solvent ethanol mol­ecule was evident with two positions being resolved for the C atoms [site occupancy of the major component = 0.612 (10)]
