tert-Butyl N-{(1S)-1-(24-dihy­droxy­benzyl­idene)hydrazinecarbon­yl-2-hy­droxy­eth­yl}carbamate ethanol monosolvate

摘要

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—H⋯O, O—H⋯N and N—H⋯O 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)].
