Abstract
In the title mol-ecule, C(16)H(25)NO(4), the non-H atoms, except for the two tert-butyl groups, are roughly planar (r.m.s. deviation of the non-H atoms = 0.086 Å). In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds, forming R(2) (2)(10) ring motifs.
摘要
在标题分子C₁₆H₂₅NO₄中，除两个叔丁基外，非氢原子大致呈平面状（非氢原子的均方根偏差 = 0.086 Å）。在晶体中，分子通过N—H⋯O氢键对连接成反演二聚体，形成R₂²(10)环模式。
