In the title compound, [Ag
2(C
8H
10NO
3S)
2(H
2O)
4], each Ag
I atom is coordinated by three water molecules and one N atom from a 2-amino-4,5-dimethylbenzenesulfonate ligand in a severely distorted tetrahedral geometry. The two Ag
I atoms are bridged by two water molecules, forming a centrosymmetric binuclear complex. The distance of 3.615 (9) Å between the two Ag
I atoms suggests that there are no Ag
Ag interaction within the binuclear molecule.

An aqueous solution (10 ml) of 2-amino-4,5-dimethylbenzenesulfonic acid (0.101 g, 0.5 mmol) was added to solid Ag2CO3 (0.069 g, 0.25 mmol) with stirring
for several minutes until no further CO2 was given off. The precipitate was
dissolved by dropwise addition of an aqueous solution of NH3 (14 M).
Then a solution of β-picoline (0.039 g, 0.5 mmol) in CH3OH (8 ml) was added
with stirring for 30 min. Crystals of the title compound were obtained by
evaporation of the solution for several days at room temperature. β-Picoline
did not react with the silversulfonate.
H atoms bonded to C atoms were positioned geometrically and refined as riding,
with C—H = 0.93Å and Uiso(H) = 1.2Ueq(C) for aromatic,
and C—H = 0.96Å and Uiso(H) = 1.5Ueq(C) for methyl
groups. H atoms bonded to N atom and water molecules were located in a
difference map and refined isotropically.

The title compound shows a binuclear structure (Fig. 1). Each AgI atom is coordinated by three water molecules with Ag—Obridge distance larger than that of Ag—Oterminal (Table 1), but both in the range of normal Ag—O distance. The AgI atom has a seriously distorted tetrahedral coodination geometry. The two AgI atoms are bridged by two water molecules, forming a binuclear structure. The Ag···Ag distance is 3.615 (9) Å, indicating no metal–metal interaction within the binuclear molecule. The molecular geometry of the title compound has been changed largely when compared with a related compound (Li et al., 2007). Adjacent molecules are connected by O—H···O and N—H···O hydrogen bonds (Table2), forming a two-dimensional supramolecular structure (Fig.2).
