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

Abstract

In the title hydrate, C23H16N4O 2 H2O, the pyrazole ring is approximately planar, with a maximum deviation of 0.023 (1) , 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?? interactions involving the centroids of the pyrazole and benzene rings.
