In the title compound, K+·C6H4BrN2O4S−·H2O, the K+ ion is hepta-coordinated by two O atoms from two different water molecules, three sulfonyl O atoms from three N-bromo-2-nitro-benzenesulfonamidate anions and two nitro O atoms from two N-bromo-2-nitro-benzenesulfonamidate anions. The S—N distance of 1.576 (4) Å is consistent with an S=N double bond. The crystal structure is stabilized by intermolecular O—HN and O—HBr hydrogen bonds which link the molecules into polymeric layers running parallel to the bc plane.

The asymmetric unit of the title salt, K+·C6H3BrCl2NO2S−·1.5H2O, contains one K+ cation, one N-bromo-2,4-dichlorobenzenesulfonamidate anion, one water molecule in general position and one water molecule located on a twofold rotation axis. The K+ cation is hepta-coordinated by three water O atoms and four sulfonyl O atoms from three symmetry-related N-bromo-2,4-dichlorobenzenesulfonamide anions. The S=N distance of 1.575 (3) Å is consistent with that of a double bond. In the crystal, the anions are linked by O—HBr and O—HN hydrogen bonds into layers parallel to the ac plane.
