The asymmetric unit of the title compound, C(13)H(18)N(2)O(3)S, contains two mol-ecules with similar conformations. In both mol-ecules, the cyclo-hexyl rings adopt chair conformations, with the attached N atom in an equatorial orientation and an intra-molecular N-H⋯O hydrogen bond generates an S(7) ring. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules and a C-H⋯O hydrogen bond is also observed. The crystal studied was a racemic twin.
标题化合物C(13)H(18)N(2)O(3)S的不对称单元包含两个构象相似的分子。在这两个分子中,环己基环呈椅式构象,连接的N原子处于平伏位置,分子内的N-H⋯O氢键形成一个S(7)环。在晶体中,N-H⋯O氢键连接分子,还观察到一个C-H⋯O氢键。所研究的晶体是一个外消旋孪晶。
