Abstract
The crystal structure of indole-3-carboxylic acid, C9H7NO2, shows the presence of centrosymmetric hydrogen-bonded cyclic carboxylic acid dimers [O⋯O = 2.649 (2) A]. These dimers are linked into a sheet structure through peripheral intermolecular hydrogen bonds between the carboxylic acid groups and the hetero-amine group of the n-glide-related indole ring [O⋯N = 3.013 (2) A].
