The asymmetric unit of the title compound, C(24)H(22)O(4), contains one half-mol-ecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49 (5)° with the terminal benzene ring. In the crystal, adjacent mol-ecules are linked through C-H⋯O inter-actions, forming a sheet structure parallel to the bc plane. The sheets are stacked along the a axis via π-π inter-actions formed between the terminal benzene rings [centroid-centroid separation = 3.7276 (6) Å].
标题化合物C(24)H(22)O(4)的不对称单元包含半个分子，另一半由晶体学反演中心产生。中心苯环与末端苯环形成的二面角为72.49 (5)°。在晶体中，相邻分子通过C-H⋯O相互作用相连，形成平行于bc平面的层状结构。这些层通过末端苯环之间形成的π-π相互作用沿a轴堆叠[质心-质心间距 = 3.7276 (6) Å]。
