The crystal structure of indole‐3‐carboxylic acid, C 9 H 7 NO 2 , shows the presence of centrosymmetric hydrogen‐bonded cyclic carboxylic acid dimers [O⋯O = 2.649 (2) Å]. 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) Å].
