3-(9H-Carbazol-9-yl)propanoic acid

Abstract

The title compound, C15H13NO2, crystallizes with two molecules (A and B) in the asymmetric unit. The carbazole ring systems of both molecules are close to planar (r.m.s deviations = 0.035 and 0.053 Å). In the crystal, A+A and B+B inversion dimers linked by pairs of O—H...O hydrogen bonds generate R22(8) loops and weak C—H...π interactions link the dimers into a three-dimensional network.
