The racemic title compound, C(23)H(28)O(2), crystallizes in the space group C2/c as a layered structure in which a centrosymmetric three hydrogen bond sequence links four molecules. Both hydroxy groups are involved in this arrangement, but they differ in that one participates in two hydrogen bonds while the other takes part in only one. Between layers, the aromatic rings take part in edge-face interactions [shortest C-H⋯C distances 3.04, 3.10 and 3.12 Å and angle between normal to planes 86.7(2)°], forming a centrosymmetric dimer. The lattice is further stabilized by C-H⋯π interactions involving both methyl (shortest C⋯C 3.82 and 3.97 Å) and methylene (shortest C⋯C 3.60 Å) groups.
外消旋标题化合物C₂₃H₂₈O₂以层状结构结晶于空间群C2/c中,其中一个中心对称的三氢键序列连接四个分子。两个羟基都参与了这种排列,但不同的是,一个羟基参与两个氢键,而另一个仅参与一个氢键。在层间,芳环参与边-面相互作用[最短C-H⋯C距离为3.04、3.10和3.12 Å,平面法线间夹角为86.7(2)°],形成一个中心对称二聚体。晶格通过涉及甲基(最短C⋯C为3.82和3.97 Å)和亚甲基(最短C⋯C为3.60 Å)基团的C-H⋯π相互作用进一步稳定。
