Abstract: The structure of the title compound, Na^+.C₆H₄Cl₂NO₂S^-·1.5H₂O, resembles the structures of the sodium salts of N-chlorobenzenesulfonamide, N-chloro-4-methylbenzenesulfonamide and N-chloro-2-methyl-4-chlorobenzenesulfonamide. There are two formula units per asymmetric unit. There is no interaction between N and Na, and the Na⁺ cation is attached to three O atoms from water molecules and three sulfonyl O atoms of three different 4,N-dichlorobenzenesulfonamide anions. There are several hydrogen bonds. The S-N distances of 1.584 (5) and 1.590 (5) Å are consistent with an S=N double bond.
