摘要：
In the title compound, C9H6ClNO2, the carboxyl group is twisted from the indole ring system by 9.00 (8)degrees. In the crystal, inversion dimers linked by pairs of O-H center dot center dot center dot O hydrogen bonds generate R-2(2)(8) loops and N-H center dot center dot center dot O hydrogen bonds link the dimers into (001) sheets. Aromatic pi-pi stacking interactions [centroid-centroid distance = 3.7185 (12) A degrees] are also observed.
