In the title compound, C(25)H(18)Cl(2)N(2)O, the cyclohexene ring has a sofa conformation. All the substituents in the cyclohexene ring, except the cyano group (which is axial) occupy equatorial positions. The crystal structure is stabilized through N-H center dot center dot center dot O hydrogen bonds, forming a chain extending along the b axis and through C-H center dot center dot center dot N and C-H center dot center dot center dot Cl interactions. It is remarkable that only one of the amino H atoms is involved in hydrogen bonding.
