چکیده
In the title compound, C(21)H(15)F(2)N(3)O(2), a pyrazole derivative bearing three aromatic substituents, the central five-membered heterocyclic ring makes dihedral angles of 1.77 (14), 3.68 (13) and 72.15 (14)° with the three benzene rings. In the crystal, C-H⋯O and C-H⋯F inter-actions connect the mol-ecules into double layers parallel to the bc plane.
