In the mol-ecule of the title compound, C(20)H(13)FN(2)O, the fluoro-phenyl ring is oriented at a dihedral angle of 72.76 (3)° with respect to the fused benzene ring. In the crystal structure, inter-molecular N-H⋯O, C-H⋯O and C-H⋯F inter-actions link the mol-ecules into chains. π-π contacts between the quinoline and benzene rings [centroid-centroid distance = 3.918 (3) Å] may further stabilize the structure. A weak C-H⋯π inter-action is also present. The O atom and two of the CH(2) groups of the quinoline ring system are disordered over two positions. The O atom was refined with occupancies of 0.489 (17) and 0.511 (17), while C and H atoms were refined with occupancies of 0.435 (13) and 0.565 (13).
在标题化合物C₂₀H₁₃FN₂O的分子中，氟苯环相对于稠合苯环的二面角为72.76 (3)°。在晶体结构中，分子间的N-H⋯O、C-H⋯O和C-H⋯F相互作用将分子连接成链。喹啉环和苯环之间的π-π接触[质心-质心距离 = 3.918 (3) Å]可能进一步稳定结构。还存在一个弱的C-H⋯π相互作用。喹啉环系统的O原子和两个CH₂基团在两个位置上无序。O原子的占有率精修为0.489 (17)和0.511 (17)，而C和H原子的占有率精修为0.435 (13)和0.565 (13)。
