In the title compound, C(27)H(36)O(3), the asymmetric unit consists of two crystallographically independent mol-ecules. The aromatic rings form dihedral angles of 17.1 (2) and 17.6 (2)° in the two molecules. In both mol-ecules, the enone groups adopt an s-cis conformation and the alkoxyl chains are in trans conformations curving out of the zigzag plane. Intra-molecular O-H⋯O hydrogen bonds involving the keto and hydr-oxy groups generate S(6) ring motifs. The mol-ecules are stacked alternately in a head-to-tail fashion along the a axis and the crystal structure is stabilized by weak C-H⋯π inter-actions. The crystal studied was a non-merohedral twin, the ratio of components being 0.788 (2):0.212 (2).
在标题化合物C(27)H(36)O(3)中，不对称单元由两个晶体学独立的分子组成。两个分子中的芳环形成的二面角分别为17.1 (2)°和17.6 (2)°。在两个分子中，烯酮基团均采取s-顺式构象，烷氧基链呈反式构象并弯曲出锯齿形平面。涉及酮基和羟基的分子内O-H⋯O氢键形成S(6)环模式。分子沿a轴以头对尾的方式交替堆积，晶体结构通过弱C-H⋯π相互作用得以稳定。所研究的晶体为非镜像孪晶，组分比例为0.788 (2):0.212 (2)。
