PotassiumN-bromo-4-chloro-2-methylbenzenesulfonamidate monohydrate

In the title compound, K(+)·C7H6BrClNO2S(-)·H2O, the K(+) cation is hepta-coordinated by two water O atoms, four sulfonyl O atoms of four different N-bromo-4-chloro-2-methyl-benzene-sulfonamidate anions, and one Br atom of one of the anions. The S-N distance of 1.584 (3) Å is consistent with an S=N double bond. In the crystal, the anions are linked into layers by O-H⋯Br and O-H⋯N hydrogen bonds.
