چکیده
The title compound, C21H17N3O5·C3H7NO, exists in an E conformation with respect to the azomethine double bond of the hydrazide mol-ecule. This mol-ecule contains an intra-molecular O-H⋯N hydrogen bond, while an inter-molecular N-H⋯O hydrogen bond links the hydrazide to the formamide mol-ecule of solvation. Nonclassical C-H⋯O inter-molecular hydrogen bonds build up a supra-molecular architecture, together with two C-H⋯π inter-actions and a weak π-π inter-action, with a centroid-centroid distance of 3.650 (13) Å.
