The triazole ring in the title mol­ecule is not quite coplanar with the six-membered ring to which it is fused, the dihedral angle between the two least-squares planes being 2.52 (6)°. In the crystal, a layer structure is formed by N—H⋯N and C—H⋯O hydrogen bonds plus slipped π-stacking inter­actions, with the fused cyclo­hexene rings projecting to either side.
