title: Potassium N-bromo-2-chloro-benzene-sulfonamidate sesquihydrate.
abstract: In the structure of the title compound, K(+)·C(6)H(4)BrClNO(2)S(-)·1.5H(2)O, the K(+) ion is hepta-coordinated by three O atoms from water mol-ecules and by four sulfonyl O atoms of N-bromo-2-chloro-benzene-sulfonamidate anions. The S-N distance of 1.582 (4) Å is consistent with an S=N double bond. The crystal structure is stabilized by inter-molecular O-H⋯Br and O-H⋯N hydrogen bonds. The asymmetric unit consits of one potassium cation, one N-bromo-2-chloro-benzene-sulfonamidate anion and one water mol-ecule in general positions and one water mol-ecule located on a twofold rotation axis.
