The structure of the title sulfonamide, C(12)H(15)Cl(2)NO(2)S, features a distorted tetra-hedral geometry for the S atom [maximum deviation: O-S-O = 120.23 (14)°]. One of the sulfonamide O atoms is coplanar with the benzene ring [C-C-S-O torsion angle = -174.5 (2)°], whereas the other lies well above the plane [C-C-S-O = 57.0 (3)°]. A chair conformation is found for the cyclo-hexyl ring. In the crystal, supra-molecular chains aligned along the c axis are formed via N-H⋯O hydrogen bonds; these are consolidated in the three-dimensional packing by C-H⋯O contacts involving the second sulfonamide O atom.
标题磺酰胺C(12)H(15)Cl(2)NO(2)S的结构中，S原子具有扭曲的四面体几何构型[最大偏差：O-S-O = 120.23 (14)°]。磺酰胺的一个O原子与苯环共平面[C-C-S-O扭转角 = -174.5 (2)°]，而另一个则位于该平面上方较远位置[C-C-S-O = 57.0 (3)°]。环己基环呈椅式构象。在晶体中，沿着c轴排列的超分子链通过N-H⋯O氢键形成；这些通过涉及第二个磺酰胺O原子的C-H⋯O接触在三维堆积中得以巩固。
