Abstract

In the title compound, C(17)H(15)FN(2)O(2), the essentially planar pyrazole ring [maximum deviation = 0.026 (1) Å] makes dihedral angles of 72.06 (7) and 33.05 (7)°, with the phenyl and fluoro-benzene rings, respectively. The dihedral angle between the two six-membered rings is 87.88 (7)°. In the crystal, inter-molecular N-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules into layers lying parallel to the bc plane.
