2-(1,2,3,4-Tetrahydro-9H-carbazol-1-ylidene)propanedinitrile

Abstract

In the title compound, C15H11N3, the cyclo­hexene ring adopts a sofa conformation. An intra­molecular N—H⋯N hydrogen bond generates an S(7) ring motif. In the crystal, mol­ecules are linked by inter­molecular N—H⋯N, C—H⋯N and C—H⋯π inter­actions into a three-dimensional network.
