The asymmetric unit of the title compound, C(18)H(23)NO(2), consists of two crystallographically independent mol-ecules bearing an adamantane cage consisting of three fused cyclo-hexane rings in almost ideal chair conformations, with C-C-C angles in the range 108.47 (16)-110.59 (15)°. Both aryl rings are essentially planar, the maximum deviation from the best plane being 0.0125 (19) Å. One conformer forms chains parallel to the b axis via N-H⋯O hydrogen bonds, whereas the second exhibits only an intra-molecular N-H⋯O hydrogen bond. The crystal structure is stabilized by further weak N-H⋯O and N-H⋯N inter-actions.
标题化合物C(18)H(23)NO(2)的不对称单元由两个晶体学独立的分子组成，每个分子带有一个金刚烷笼，该笼由三个几乎呈理想椅式构象的稠合环己烷环组成，C-C-C键角在108.47 (16)-110.59 (15)°范围内。两个芳环基本呈平面状，与最佳平面的最大偏差为0.0125 (19) Å。一种构象通过N-H⋯O氢键形成平行于b轴的链，而另一种仅表现出分子内N-H⋯O氢键。晶体结构通过进一步的弱N-H⋯O和N-H⋯N相互作用得以稳定。
