(2E)-2-[1-(2-Hy­droxy-4-meth­oxy­phenyl)ethyl­idene]-N-phenyl­hydrazine­carbox­amide monohydrate

The title compound, C(16)H(17)N(3)O(3)·H(2)O, exists in the E conformation with respect to the azomethine C=N double bond. While the phenyl ring is almost coplanar with the central hydrazinecarboxamide group [dihedral angle = 14.18 (11)°], it is twisted slightly with respect to the other aromatic ring in the mol­ecule, with a dihedral angle of 22.88 (13)°. The packing is dominated by O—H⋯O, N—H⋯O and C—H⋯O hydrogen-bond inter­actions, forming a three-dimensional supra­molecular structure which is augmented by two types of C—H⋯π inter­actions. An intramolecular O—H⋯N interaction is also present in the molecule.
