Abstract: The title compound, C31H24F4N2O, exists in a chair-boat conformation with an equatorial orientation of the 2-fluorophenyl groups on both sides of the secondary amino group of the chair form. The benzene rings in the `chair' part are inclined to each other at 19.4 (1)°, while the equivalent angle between the benzene rings in the `boat' part is 75.6 (1)°. One F atom was treated as disordered over two positions in a 0.838 (4):0.162 (4) ratio. In the crystal, N-H...O hydrogen bonds link the molecules into chains along [001] and these chains are held together via weak N-H...F and C-H...F interactions.
