1-[5-(4-Methoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]ethanone

The title molecule, C18H18N2O2, is V-shaped with the pyrazoline moiety being inclined to the adjacent phenyl ring by an angle of 6.49 (9)°, while the 4-methoxy-substituted ring is inclined to the pyrazoline ring by 82.99 (9)°. In the crystal, adjacent molecules are linked by C—H...O interactions, forming chains propagating in [100]. There are also C—H...π interactions involving adjacent molecules and those related by an inversion center.
