The title compound, C11H8N2O, crystallizes with two crystallographically independent molecules in the asymmetric unit which are approximately perpendicular to each other [79.97 (6)°]. The indole ring system is planar [r.m.s. deviation = 0.010 (1) Å]. The crystal structure is stabilized by intermolecular C-HN and N-HO interactions.
