title: 2-(2-Chloro-6,7-dimethyl-quinolin-3-yl)-2,3-dihydro-quinolin-4(1H)-one.
abstract: In the title mol-ecule, C(20)H(17)ClN(2)O, the dihedral angle between the mean plane of the quinoline ring system and the benzene ring of the dihydro-quinolinone moiety is 57.84 (8)°. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of inter-molecular N-H⋯N hydrogen bonds. These dimers are further stabilized by weak π-π stacking inter-actions between pyridine rings with a centroid-centroid distance of 3.9414 (12) Å.
