In the title compound, [K(C7H6Cl2NO2S)(H2O)]n, the K+ cation is heptacoordinated by two water O atoms, a sulfonyl O atom from each of four different N,4-dichloro-2-methylbenzenesulfonamidate anions and a Cl atom of one of the anions. Further, K-O-K bridges form extensive polymeric chains along the b axis. In the crystal structure, the anions are linked into layers parallel to (100) by O-HCl and O-HN hydrogen bonds.
