(4-Amino-3-methyl­benzene­sulfonato)tri-μ-aqua-penta­aqua­disodium 4-amino-3-methyl­benzene­sulfonate

In the title compound, [Na(2)(C(7)H(8)NO(3)S)(H(2)O)(8)](C(7)H(8)NO(3)S), one Na(+) ion is bonded to six water mol­ecules in a distorted octa­hedral arrangement while the other is bonded to five water mol­ecules and one O atom of a 4-amino-3-methyl­benzene­sulfonate anion, also yielding a distorted NaO(6) octa­hedron. Three of the water molecules bridge the metal ions and an intra­molecular O—H⋯O hydrogen bond helps to establish the conformation. In the crystal, the component species inter­act by way of O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds.
