In the title molecule, C22H16N2O, the phenyl ring is twisted slightly Jandy Levolor Parts 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—H.O hydrogen bonds T-shirt 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).
