The reaction of silver nitrate with 5-chloro-2-hy­droxy­benzene­sulfonic acid in the presence of ammonia yielded the title salt, (NH4)[Ag(NH3)2](C6H4ClO4S)2·3H2O. The AgI ion shows linear coordination [N—Ag—N = 175.2 (1) °]. The ammonium and diamminesilver cations, the benzene­sulfonate anion and the lattice water mol­ecules inter­act through an intricate network of N—H⋯O and O—H⋯O hydrogen bonds to form a three-dimensional network.
