ABSTRACT
In the title compound, C13H13N3O, the tetrahydrobenzene ring adopts a half-boat (envelope) conformation. The mean plane of the tetrahydronaphthalene ring system forms a dihedral angle of 9.56 (6)° with the mean plane of the cyanoacetohydrazide group. In the crystal, inversion dimers linked by pairs of N—H...O hydrogen bonds generate R22(8) loops. The dimers are connected by C—H...N hydrogen bonds into a chain propagating along [101]. The crystal packing also features C—H...π interactions.
