Abstract
In the molecule of the title compound, C19H17NO2, 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)°. Intramolecular C—H⋯O interactions result in the formation of five- and six-membered rings having planar and envelope conformations, respectively. In the crystal structure, intermolecular C—H⋯O interactions link the molecules 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 interactions are also found.

We report the synthesis and crystal structure of the title compound
The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
