In the title compound, C11H10N2O, the O atom and the C atom of the methylene group deviate only slightly [0.029 (3) and 0.055 (3) Å, respectively] from the approximately planar ring system (r.m.s. deviation = 0.013 Å). In the crystal, N—HO hydrogen bonds link the molecules into zigzag chains running along the b axis.

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 [010]. Aromatic π–π stacking interactions [minimum centroid–centroid separation = 3.663 (3) Å] are also observed.
