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.
标题化合物Na⁺·C₉H₇N₄O₅S⁻·2H₂O在亚胺C=N键周围呈Z构型，在C(O)NH₂基团周围呈E构型，通过两个分子内氢键得以稳定。堆积作用受Na⁺阳离子与周围O原子之间的离子相互作用支配。离子单元Na⁺和2-氧代-3-氨基脲基-2,3-二氢-1H-吲哚-5-磺酸盐形成在bc平面延伸的层。这些层通过涉及水分子的氢键相连。
