Abstract
There are three independent 3-hydroxyimino-1-methylindolin-2-one molecules and a water molecule in the asymmetric unit of the title compound, 3C9H8N2O2·H2O. The crystal packing is stablized by O—H⋯O and O—H⋯Nhydrogen bonds between 3-hydroxyimino-1-methylindolin-2-one molecules and the water molecule and weak π–π stacking interactions [centroid–centroid distances in the range 3.446 (2)–3.983 (2) Å], forming a two-dimensional network.
