Abstract
The asymmetric unit of the title compound, C(29)H(50)O(2), contains two mol-ecules; one mol-ecule is linked to the other by two O-H⋯O hydrogen bonds, whereas only one of the hydr-oxy groups of the second mol-ecule is involved in hydrogen bonding. This gives rise to a chain that runs along the a axis of the monoclinic unit cell.
摘要
标题化合物C(29)H(50)O(2)的不对称单元包含两个分子；一个分子通过两个O—H⋯O氢键与另一个分子相连，而第二个分子只有一个羟基参与氢键形成。这形成了一条沿单斜晶胞a轴延伸的链。
