Abstract: In the title molecule, C₂₂H₁₆N₂O, the phenyl ring is twisted slightly with respect to the plane of the central pyrazole ring [dihedral angle = 14.8 (2)°]; the central ring is connected to the naphthyl ring through a -CH=CH-C(=O)- fragment, whose C=C double bond has an E configuration. The pyrazole ring and naphthalene ring system are twisted by 46.3 (1)°. Weak intermolecular C-HO hydrogen bonds link the molecules, forming supramolecular chains running along the a axis. The crystal studied was a non-merohedral twin with a component ratio of 0.544 (2):0.456 (2).
