چکیده
The title mol-ecule, C(9)H(8)BrNO, approximates a full planar conformation. The inter-planar angle between the benzene and five-membered rings of the indoline system is 1.38 (1)°. There is an obvious π-delocalization involving the N-C=O group in the five-membered ring, which is greater than that involving the N-C C(benzene) group.

There are three independent 3-hy-droxy-imino-1-methyl-indolin-2-one mol-ecules and a water mol-ecule in the asymmetric unit of the title compound, 3C(9)H(8)N(2)O(2)·H(2)O. The crystal packing is stablized by O-H⋯O and O-H⋯Nhydrogen bonds between 3-hy-droxy-imino-1-methyl-indolin-2-one mol-ecules and the water mol-ecule and weak π-π stacking inter-actions [centroid-centroid distances in the rang...
