Poly[μ-aqua-μ-(N,4-di­chloro-2-methyl­benzene­sulfonamidato)-potassium]

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—H...Cl and O—H...N hydrogen bonds.
