Crystal structure and DFT study of benzyl 1-benzyl-2-oxo-1,2-di­hydro­quinoline-4-carboxyl­ate

In the title quinoline derivative, C(24)H(19)NO(3), the two benzyl rings are inclined to the quinoline ring mean plane by 74.09 (8) and 89.43 (7)°, and to each other by 63.97 (10)°. The carboxyl­ate group is twisted from the quinoline ring mean plane by 32.2 (2)°. There is a short intra­molecular C—H⋯O contact forming an S(6) ring motif. In the crystal, mol­ecules are linked by bifurcated C—H,H⋯O hydrogen bonds, forming layers parallel to the ac plane. The layers are linked by C—H⋯π inter­actions, forming a supra­molecular three-dimensional structure.
