title: Crystal structure of 2-amino-4-(4-chloro-phen-yl)-1-(4-methyl-phen-yl)-5-oxo-1,4,5,6,7,8-hexa-hydro-quinoline-3-carbo-nitrile.
abstract: In the title compound, C23H20ClN3O, each of the cyclo-hexene and 1,4-di-hydro-pyridine rings of the 1,4,5,6,7,8-hexa-hydro-quinoline ring system adopts a twisted-boat conformation. The dihedral angle between the two benzene rings is 11.52 (7)°. In the crystal, mol-ecules are linked through a pair of amino-nitrile N-H⋯N hydrogen bonds, forming inversion dimers. These assemble into a three-dimensional network via C-H⋯O and C-H⋯π inter-actions.
