1-[3,5-Bis(4-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl]ethanone
In the asymmetric unit of the title compound, C(17)H(14)F(2)N(2)O, there are three independent molecules (A, B and C) which differ slightly in the relative orientations of the two fluorophenyl rings. In molecules A and C one of the fluorophenyl rings is disordered over two positions, with occupa...

Sumario: | In the asymmetric unit of the title compound, C(17)H(14)F(2)N(2)O, there are three independent molecules (A, B and C) which differ slightly in the relative orientations of the two fluorophenyl rings. In molecules A and C one of the fluorophenyl rings is disordered over two positions, with occupancy ratios of 0.72 (2):0.28 (2) for molecule A and 0.67 (2):0.33 (2) for molecule C. The dihedral angle between the two fluorophenyl rings in the independent molecules lie in the range 70.3 (3)–84.0 (3)°. In the crystal structure, the molecules are linked via intermolecular C—H⋯O and C—H⋯F hydrogen bonds and π⋯π stacking interactions [centroid–centroid distance = 3.7508 (13) Å], forming a three-dimensional network. |
