Abstract
In the structure of the title compound, K(+)·C(7)H(7)BrNO(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-methyl-benzene-sulfonamide anions. The S-N distance of 1.577 (5) Å is consistent with an S=N double bond. The crystal structure comprises sheets in the ac plane which are further stabilized by O-H⋯Br and O-H⋯N hydrogen bonds.
摘要
在标题化合物K(+)·C(7)H(7)BrNO(2)S(-)·1.5H(2)O的结构中，K(+)离子由三个水分子的O原子和N-溴-2-甲基苯磺酰胺阴离子的四个磺酰基O原子七配位。S-N键长为1.577 (5) Å，与S=N双键相符。晶体结构在ac平面上由片层组成，通过O-H⋯Br和O-H⋯N氢键进一步稳定。
