Abstract: The title molecule, C₉H₈BrNO, approximates a full planar conformation. The interplanar angle between the benzene and five-membered rings of the indoline system is 1.38 (1)°. There is an obvious -delocalization involving the N-C=O group in the five-membered ring, which is greater than that involving the N-CC(benzene) group.
