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 R 2 2(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.
