In the title compound, K(+)·C(6)H(4)BrN(2)O(4)S(-)·H(2)O, the K(+) ion is hepta-coordinated by two O atoms from two different water mol-ecules, three sulfonyl O atoms from three N-bromo-2-nitro-benzene-sulfonamidate anions and two nitro O atoms from two N-bromo-2-nitro-benzene-sulfonamidate anions. The S-N distance of 1.576 (4) Å is consistent with an S=N double bond. The crystal structure is stabilized by inter-molecular O-H⋯N and O-H⋯Br hydrogen bonds which link the molecules into polymeric layers running parallel to the bc plane.
在标题化合物K⁺·C₆H₄BrN₂O₄S⁻·H₂O中，K⁺离子由两个不同水分子中的两个O原子、三个N - 溴 - 2 - 硝基苯磺酰胺阴离子中的三个磺酰基O原子以及两个N - 溴 - 2 - 硝基苯磺酰胺阴离子中的两个硝基O原子七配位。S - N键长为1.576(4) Å，与S = N双键相符。晶体结构通过分子间O - H⋯N和O - H⋯Br氢键得以稳定，这些氢键将分子连接成平行于bc平面的聚合物层。
