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.
在标题化合物C(16)H(15)FN(2)O(2)的分子中，苯环以88.61 (3)°的二面角取向。五元环呈信封构象。分子内的C-H⋯N氢键导致形成两个平面五元环。在晶体结构中，分子间的N-H⋯O和C-H⋯F氢键连接分子，形成R(2) (2)(8)和R(2) (2)(18)环基序。弱的C-H⋯π相互作用可能进一步稳定该结构。
