title: (4-Amino-3-methyl-benzene-sulfonato)tri-μ-aqua-penta-aqua-disodium 4-amino-3-methyl-benzene-sulfonate.
abstract: 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 mol-ecules in a distorted octa-hedral arrangement while the other is bonded to five water mol-ecules and one O atom of a 4-amino-3-methyl-benzene-sulfonate anion, also yielding a distorted NaO(6) octa-hedron. Three of the water molecules bridge the metal ions and an intra-molecular O-H⋯O hydrogen bond helps to establish the conformation. In the crystal, the component species inter-act by way of O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds.
