The asymmetric unit of the title compound, C20H24N2O2S, contains two independent mol-ecules having very similar geometries. The main N-(6-meth-oxy-1,3-benzo-thia-zol-2-yl)acetamide moiety adopts an almost planar structure (r.m.s. deviations of 0.091 and 0.051 Å for the two independent molecules). The adamantyl substituent occupies the gauche position relative to the C-N bond of the acetamide moiety [the corresponding N-C-C-C dihedral angles are -100.3 (3) and -96.5 (3)° for the two independent mol-ecules]. In the crystal, the two independent mol-ecules form a dimer via a pair of N-H⋯N hydrogen bonds. The dimers are further linked by C-H⋯O hydrogen bonds and attractive S⋯S [3.622 (2) Å] inter-actions into ribbons along [100].
标题化合物C20H24N2O2S的不对称单元包含两个几何结构非常相似的独立分子。主要的N-(6-甲氧基-1,3-苯并噻唑-2-基)乙酰胺部分采用几乎平面的结构（两个独立分子的均方根偏差分别为0.091和0.051 Å）。金刚烷基取代基相对于乙酰胺部分的C-N键处于gauche位置[两个独立分子对应的N-C-C-C二面角分别为-100.3(3)和-96.5(3)°]。在晶体中，两个独立分子通过一对N-H⋯N氢键形成二聚体。这些二聚体通过C-H⋯O氢键和有吸引力的S⋯S [3.622(2) Å]相互作用进一步连接成沿[100]方向的带状结构。
