3,5-Bis(4-fluoro-phen-yl)-1-phenyl-4,5-dihydro-1H-pyrazole.


ABSTRACT: In the title compound, C(21)H(16)F(2)N(2), the dihedral angle between the fluoro-phenyl groups is 66.34?(8)°, and the dihedral angle between the envelope-configured pyrazole group (N/N/C/C/C) and the benzene ring is 11.50?(9)°. The dihedral angles between the benzene and the two fluoro-substituted phenyl groups are 77.7?(6) and 16.7?(5)°. Weak C-H?? interactions contribute to the stability of the crystal structure.
