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.
