In the mol-ecule of the title compound, C(24)H(28)O(4), the three six-membered rings of the xanthene system are not planar, having envelope, boat and envelope conformations. In the crystal structure, C-H⋯O hydrogen bonds link the mol-ecules, generating centrosymmetric R(2) (2)(12), R(4) (4)(28) and R(2) (2)(16) ring motifs and forming a three-dimensional network.

在标题化合物C₂₄H₂₈O₄的分子中，呫吨系统的三个六元环不是平面的，具有信封式、船式和信封式构象。在晶体结构中，C—H⋯O氢键连接分子，产生中心对称的R₂²(12)、R₄⁴(28)和R₂²(16)环 motif，并形成三维网络。
