In the title compound, Na+·C6H4BrClNO2S−·1.5H2O, one water molecule has crystallographically imposed twofold symmetry. The Na+ cation shows a pseudo-octahedral coordination provided by three O atoms of water molecules and three sulfonyl O atoms of different N-bromo-2-chlorobenzenesulfonamidate anions. The S—N distance of 1.579 (6) Å is consistent with an S=N double-bond character. The crystal structure is stabilized by O—H⋯Br, O—H⋯N and O—H⋯O hydrogen bonds.
