Sodium 2-oxo-3-semicarbazono-2,3-dihydro-1H-indole-5-sulfonate dihydrate.
The title compound, Na+.C9H7N4O5S-.2H2O, presents a Z configuration around the imine C=N bond and an E configuration around the C(O)NH2 group, stabilized by two intramolecular hydrogen bonds. The packing is governed by ionic interactions between the Na+ cation and the surrounding O atoms. The ionic unit, Na+ and 2-oxo-3-semicarbazono-2,3-dihydro-1H-indole-5-sulfonate, forms layers extending in the bc plane. The layers are connected by hydrogen bonds involving the water molecules.
