2,5-Dichloro-N-cyclo-hexyl-benzene-sulfonamide.

ABSTRACT: 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.
