N′-[(E)-4-Benzyloxy-2-hydroxybenzylidene]-4-nitrobenzohydrazide dimethylformamide monosolvate

Abstract

The title compound, C21H17N3O5·C3H7NO, exists in an E conformation with respect to the azomethine double bond of the hydrazide mol­ecule. This mol­ecule contains an intra­molecular O—H⋯N hydrogen bond, while an inter­molecular N—H⋯O hydrogen bond links the hydrazide to the formamide mol­ecule of solvation. Nonclassical C—H⋯O inter­molecular hydrogen bonds build up a supra­molecular architecture, together with two C—H⋯π inter­actions and a weak π–π inter­action, with a centroid–centroid distance of 3.650 (13) Å.
