Abstract

In the asymmetric unit of the title compound, C\sb 17H\sb 14F\sb 2N\sb 2O, there are three independent mol\-ecules (\it A, \it B and \it C) which differ slightly in the relative orientations of the two fluoro\-phenyl rings. In mol\-ecules \it A and \it C one of the fluoro\-phenyl rings is disordered over two positions, with occupancy ratios of 0.72(2):0.28(2) for mol\-ecule \it A and 0.67(2):0.33(2) for mol\-ecule \it C. The dihedral angle between the two fluoro\-phenyl rings in the independent mol\-ecules lie in the range 70.3(3)—84.0(3)\circ. In the crystal structure, the mol\-ecules are linked \it via inter\-molecular C—-H⋅sO and C—-H⋅sF hydrogen bonds and π⋅sπ stacking inter\-actions centroid{--}centroid distance = 3.7508(13){\AA}, forming a three-dimensional network.
