title: 2-(6-Chloro-2,3,4,9-tetra-hydro-1H-carbazol-1-yl-idene)propane-dinitrile.
abstract: The mol-ecular conformation of the title compound, C(15)H(10)ClN(3), is stabilized by an intra-molecular N-H⋯N hydrogen bond with an S(7) ring motif. The crystal packing is controlled by N-H⋯N and C-H⋯N inter-molecular inter-actions. One of the methyl-ene groups of the cyclo-hexene ring is disordered over two positions with refined occupancies of 0.457 (12) and 0.543 (12).
