摘要：The organic anion of the title compound, {[Na(C(15)H(9)O(10)S)(H(2)O)(2)]center dot H(2)O} (n) {systematic name: poly[[diaqua[mu-2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4-oxo-4H-chromene-8-sulfonato]sodium] monohydrate]}, has a nearly planar structure. The Na atom is six-coordinated by O atoms, two from water molecules and four from the anion. The dihedral angle between the ring systems in the anion is 10.1 (1)degrees. Intramolecular O-H...S and O-H...O interactions occur. In the crystal structure, an extensive network of classical intermolecular O-H...S and O-H...O hydrogen bonds forms layers along the c axis.
