title: 2-(2,3,4,9-Tetra-hydro-1H-carbazol-1-ylidene)propane-dinitrile.
abstract: In the title mol-ecule, C(15)H(11)N(3), the dihedral angle between the benzene ring and the fused pyrrole ring is 1.07 (5)°. The cyclo-hexene ring adopts an envelope conformation: the dicyano-methyl-ene group at position 1 has a coplanar orientation. An intra-molecular N-H⋯N hydrogen bond generates an S(7) ring motif. Inter-molecular N-H⋯N hydrogen bonds form an R(2) (2)(14) ring in the crystal. A C-H⋯π inter-action involving the benzene ring is also found in the structure.
