N′-[(E)-(3-Phenyl-1H-pyrazol-4-yl)methyl­idene]naphtho­[2,1-b]furan-2-carbohydrazide monohydrate

In the title hydrate, C(23)H(16)N(4)O(2)·H(2)O, the pyrazole ring is approximately planar, with a maximum deviation of 0.023 (1) Å, and makes dihedral angles of 28.63 (6) and 46.44 (7)° with the naphtho­[2,1-b]furan ring system and the benzene ring, respectively, In the crystal, O—H⋯N, O—H⋯O, N—H⋯O, N—H⋯N, C—H⋯O and C—H⋯N hydrogen bonds link the mol­ecules, forming sheets lying parallel to the ab plane. The crystal structure also features C—H⋯π inter­actions involving the centroids of the pyrazole and benzene rings.
