Abstract

In the mol-ecule of the title compound, C(16)H(15)FN(2)O(2), the benzene rings are oriented at a dihedral angle of 88.61 (3)°. The five-membered ring adopts an envelope conformation. Intra-molecular C-H⋯N hydrogen bonds result in the formation of two planar five-membered rings. In the crystal structure, inter-molecular N-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules, forming R(2) (2)(8) and R(2) (2)(18) ring motifs. Weak C-H⋯π inter-actions may further stabilize the structure.
