N′-[(E)-4-Benzyloxy-2-hydroxybenzylidene]-4-nitrobenzohydrazide dimethylformamide monosolvate
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—HN hydrogen bond, while an intermolecular N—HO hydrogen bond links the hydrazide to the formamide molecule of solvation. Nonclassical C—HO intermolecular hydrogen bonds build up a supramolecular architecture, together with two C—Hπ interactions and a weak π–π interaction, with a centroid–centroid distance of 3.650 (13) Å.

In the title compound, C24H18S, the dihedral angles between the phenyl ring and the two benzene rings of the anthracene moiety are 51.92 (9) and 68.24 (9)°, whereas the dihedral angle between the two anthracene benzene rings is 120.13 (9)°. The three non-aromatic six-membered rings are in boat conformations, while the five-membered ring has an envelope conformation on the S atom. In the crystal, there are three C—Hπ interactions, which facilitate the packing of the molecules.
