The title compound, C13H13NO, crystallizes with four independent molecules in the asymmetric unit. The 12-membered penta[b]indole rings are essentially planar, with maximum deviations ranging from 0.034 (4) to 0.036 (4) Å in the four unique molecules. In the crystal, weak C—H
O interactions are observed, which link the molecules into chains along [010].

The 12-membered cyclopenta[b]indole ring system in the title compound, C13H13NO2, deviates only slightly from planarity (r.m.s. deviation = 0.051 Å). In the crystal, N—HO and O—HO hydrogen bonds link the molecules into sheets parallel to (100). The five-membered cyclopentanone ring is in slightly distorted envelope conformation with the C atom bearing the hydroxy substituent as the flap.
