Crystal structure of 2-amino-4-(4-chlorophenyl)-1-(4-methylpheny1)-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carbo-nitrile

In the title compound, C23H20ClN3O, each of the cyclohexene and 1,4-dihydropyridine rings of the 1,4,5,6,7,8-hexahydro-quinoline ring system adopts a twisted-boat conformation. The dihedral angle between the two benzene rings is 11.52 (7)degrees. In the crystal, molecules are linked through a pair of amino-nitrile N-H center dot center dot center dot N hydrogen bonds, forming inversion dimers. These assemble into a three-dimensional network via C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions
