In the mol-ecule of the title compound, C(19)H(17)NO(2), the quinoline ring system is planar [maximum deviation 0.021 (3) Å] and oriented with respect to the phenyl ring at a dihedral angle of 80.44 (4)°. Intra-molecular C-H⋯O inter-actions result in the formation of five- and six-membered rings having planar and envelope conformations, respectively. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into centrosymmetric dimers forming R(2) (2)(12) ring motifs. π-π contacts between the rings of the quinoline system [centroid-to-centroid distance = 3.812 (1) Å] may further stabilize the structure. Two weak C-H⋯π inter-actions are also found.
在标题化合物C(19)H(17)NO(2)的分子中，喹啉环系呈平面状[最大偏差0.021 (3) Å]，相对于苯环的二面角为80.44 (4)°。分子内C-H⋯O相互作用分别导致形成具有平面和信封构象的五元环和六元环。在晶体结构中，分子间C-H⋯O相互作用将分子连接成中心对称二聚体，形成R(2) (2)(12)环基序。喹啉体系环之间的π-π接触[质心到质心距离 = 3.812 (1) Å]可能进一步稳定结构。还发现了两种弱C-H⋯π相互作用。
