N′-[(Z)-4-Methylbenzylidene]-4-nitrobenzohydrazide monohydrate

In the title compound, C15H13N3O3·H2O, the two benzene rings form a dihedral angle of 2.03 (2)°. In the crystal structure, adjacent hydrazide molecules are linked into dimers by water molecules; these dimers are then stacked along the b axis. Intermolecular O—H...O, O—H...N and C—H...O hydrogen bonds and a π–π stacking interaction between the nitrobenzene and tolyl rings with a centroid–centroid distance of 3.8208 (3) Å are observed. There is also a short O...N contact [2.6824 (7) Å]
