title: 2-(6-Methyl-2,3,4,9-tetra-hydro-1H-carbazol-1-yl-idene)propane-dinitrile.
abstract: In the title compound, C(16)H(13)N(3), the cyclo-hexene ring adopts a sofa conformation. An intra-molecular N-H⋯N hydrogen bond generates an S(7) ring motif. In the crystal, the mol-ecules are linked by pairs of N-H⋯N inter-actions, forming centrosymmetric dimers with an R(2) (2)(14) motif.
