Abstract: In the title compound, C10H7ClN2, the carbonitrile group is twisted away from the plane of the indole ring system [Ccy-Cme-Car-Car = -44.7 (8)°; cy = cyanide, me = methylene and ar = aromatic]. In the crystal, N-HN hydrogen bonds link the molecules into C(7) chains propagating in . Aromatic - stacking interactions [minimum centroid-centroid separation = 3.663 (3) Å] are also observed.
