چکیده
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)°, respectively, with the remaining two benzene rings. Weak inter-molecular C-H⋯F hydrogen bonds link the mol-ecules into chains propagated in [101]. The crystal packing exhibits weak π-π inter-actions as evidenced by relatively short distances between the centroids of the aromatic rings [3.820 (7) and 3.971 (5) Å]. A MOPAC PM3 optimization of the mol-ecular geometry in vacuo supports a suggestion that inter-molecular forces have a significnt influence on the mol-ecular conformation in the crystal.
