The title compound, C(12)H(18)N(2)O, was synthesized by the reaction of cyclo-hexa-none and 2-amino-cyclo-pent-1-enecarbonitrile. In the mol-ecule of the title compound, the six-carbon ring displays a chair conformation, the six-membered 1,3-diaza ring and the cyclo-pentene ring both assume envelope conformations. Supra-molecular aggregation is achieved by N-H⋯O hydrogen bonds.
