Abstract

In the title compound, C(38)H(36)F(2)N(4)O(4), the pyrazole rings form dihedral angles of 50.02 (4) and 18.05 (4)° with their attached fluorobenzene rings, and make dihedral angles of 76.08 (4) and 73.54 (5)° with the aromatic ring of the attached phen-oxy group. In the crystal, the molecules are connected by weak C-H⋯π inter-actions.
