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

Abstract

In the title mol­ecule, C15H11N3, the dihedral angle between the benzene ring and the fused pyrrole ring is 1.07 (5)°. The cyclo­hexene ring adopts an envelope conformation: the dicyano­methyl­ene group at position 1 has a coplanar orientation. An intra­molecular N—H⋯N hydrogen bond generates an S(7) ring motif. Inter­molecular N—H⋯N hydrogen bonds form an R 2 2(14) ring in the crystal. A C—H⋯π inter­action involving the benzene ring is also found in the structure.
