The molecule of the title pyrazole derivative, 3,5-diphenyl-1-(phenylacetyl)-4,5-dihydro-1H-pyrazol, C23H20N2O, is twisted. The compound crystallizes in the monoclinic sp. gr. I2/a with a = 15.3502(13) Å, b = 12.7576(8) Å, c = 19.625(2) Å, β = 106.639(7)°, and Z = 8. In the compound, the phenyl rings form dihedral angles of 12.01(13)°, 80.36(8)°, and 86.95(9)° with the mean plane of the pyrazole ring...
In the title compound, C18H18N2O, the whole molecule is not planar but the phenyl ring systems are planar individually. The central pyrazole ring system is twisted with puckering parameters Q = 0.1610(18) Å and φ = 82.2(6)°. The crystallographic structure is stabilized by C-H⋯N type intramolecular hydrogen bond, generating ring motif R(5).
