6-Fluoro-1H-indole-3-carboxylic acid
In the title compound, C9H6FNO2, all the non-H atoms are approximately coplanar, the carboxy O atoms deviating by 0.0809 and −0.1279 Å from the indole plane. In the crystal, O—H⋯O hydrogen bonds link the molecules into dimers which are linked via N—H⋯O hydrogen bonds and π–π interactions [centroid–centroid distance = 3.680 (2) Å
5-Chloro-1H-indole-3-carboxylic acid
In the title compound, C9H6ClNO2, the carboxyl group is twisted from the indole ring system by 9.00 (8)°. In the crystal, inversion dimers linked by pairs of O—H⋯O hydrogen bonds generate R
2
2(8) loops and N—H⋯O hydrogen bonds link the dimers into (001) sheets. Aromatic π–π stacking interactions [centroid–centroid distance = 3.7185 (12) A °] are also observed

2-(4-Bromo-1H-indol-3-yl)acetonitrile
In the title compound, C10H7BrN2, the non-H atoms, except the N atom of the acetonitrile group and the C atom bonded to it, lie in the least-squares plane defined by the atoms of the indole ring system (r.m.s deviation = 0.019 Å), with the N and C atom of the cyano group displaced by 2.278 (1) and 1.289 (1) Å, respectively, out of that plane. In the crystal, N—H⋯N hydrogen bonds link the molecules into a C(7) chain along [100]
