摘要：

In the title compound, C(21)H(15)F(3)N(2), the benzene ring bonded to the central C atom forms dihedral angles of 77.5 (7) and 89.0 (5)degrees, respectively, with the remaining two benzene rings. Weak intermolecular C-H center dot center dot center dot F hydrogen bonds link the molecules into chains propagated in [101]. The crystal packing exhibits weak pi-pi interactions as evidenced by relatively short distances between the centroids of the aromatic rings [3.820 (7) and 3.971 (5) angstrom]. A MOPAC PM3 optimization of the molecular geometry in vacuo supports a suggestion that intermolecular forces have a significnt influence on the molecular conformation in the crystal.
