In the title compound, C(27)H(26)O(4), each of the cyclo-hexenone rings adopts a half-chair conformation. The dihedral angle between the two phenyl rings is 89.53 (5)°. The hy-droxy and carbonyl O atoms face each other and are orientated to allow the formation of two intra-molecular O-H⋯O hydrogen bonds, which are typical of xanthene derivatives.
在标题化合物C₂₇H₂₆O₄中,每个环己烯酮环均呈半椅式构象。两个苯环之间的二面角为89.53 (5)°。羟基和羰基氧原子相互面对并取向,以允许形成两个分子内O-H⋯O氢键,这是呫吨衍生物的典型特征。
