N'-[(E)-(3-Phenyl-1H-pyrazol-4-yl)methyl-idene]naphtho-[2,1-b]furan-2-carbohydrazide monohydrate.

ABSTRACT: 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 mol-ecules, forming sheets lying parallel to the ab plane. The crystal structure also features C-H⋯π inter-actions involving the centroids of the pyrazole and benzene rings.

2-Methyl-1-(phenyl-sulfon-yl)naphtho[2,1-b]furan.

Project description:The title compound, C(19)H(14)O(3)S, was prepared by the oxidation of 2-methyl-1-(phenyl-sulfan-yl)naphtho[2,1-b]furan with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 87.13 (4)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.850 (2) Å] and weak C-H⋯π inter-actions. In addition, there are also intra-molecular C-H⋯O inter-actions.
