2-(6-Chloro-2,3,4,9-tetrahydro-1H-carbazol-1-ylidene)propanedinitrile
Abstract
The molecular conformation of the title compound, C15H10ClN3, is stabilized by an intramolecular N—H...N hydrogen bond with an S(7) ring motif. The crystal packing is controlled by N—H...N and C—H...N intermolecular interactions. One of the methylene groups of the cyclohexene ring is disordered over two positions with refined occupancies of 0.457 (12) and 0.543 (12).
