In the molecular structure of the title compound, C(21)H(44)O(2), the hydrocarbon skeleton has an all-trans conformation. One of the terminal hydroxyl groups is also trans with respect to the skeleton, while the other is gauche. In the crystal structure, the molecules lie parallel to the b axis, forming layers with a thickness of b/2. The packing is similar to that in the smectic A phase of liquid crystals. These features are similar to those of the homologues with an odd number of C atoms, but different from those with an even number.
在标题化合物C(21)H(44)O(2)的分子结构中，烃骨架具有全反式构象。其中一个末端羟基相对于骨架也是反式的，而另一个是邻位交叉式的。在晶体结构中，分子平行于b轴排列，形成厚度为b/2的层。堆积方式类似于液晶的近晶A相。这些特征与具有奇数个碳原子的同系物相似，但与具有偶数个碳原子的同系物不同。
