Sodium N-bromo-2-chloro­benzene­sulfonamidate sesquihydrate

摘要

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.
