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

ABSTRACT: In the title compound, C(17)H(15)FN(2)O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20?(5)°. In the crystal, a pair of C-H?O hydrogen bonds link neighbouring mol-ecules, forming an inversion dimer. The crystal structure is further consolidated by C-H?? inter-actions and by a ?-? inter-action with a centroid-centroid distance of 3.7379?(6)?Å.

In the title compound, C(17)H(15)FN(2)O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20 (5)°. In the crystal, a pair of C-H⋯O hydrogen bonds link neighbouring mol-ecules, forming an inversion dimer. The crystal structure is further consolidated by C-H⋯π inter-actions and by a π-π inter-action with a centroid-centroid distance of 3.7379 (6) Å. ...[more]
