1-(1-Hydroxy-8-methyl-9H-carbazol-2-yl)ethanone

Abstract

The title compound, C15H13NO2, crystallizes with four independent molecules (A, B, C and D) in the asymmetric unit. The carbazole units are almost planar [maximum deviations = 0.015 (3) for A, 0.024 (3) for B, 0.026 (3) for C and 0.046 (3) Å for D]. In all four molecules, there is an O—H...O hydrogen bond involving the hydroxy substituent and the carbonyl O atom of the adjacent acetyl group, which forms a six-membered ring. In the crystal, the four independent molecules are linked via N—H...O and C—H...O interactions.
