In the title compound, C(22)H(28)O(3), the dihedral angle between the benzene rings is 3.47 (13)° and the five-membered furan ring is essentially planar with a largest deviation of 0.0052 (14) Å. The Csp(2)-Csp(2) bond length between the two benzene rings [1.443 (3) Å] is considerably shorter than those between the benzene and tertiary C atoms [1.538 (3) and 1.530 (3) Å], which are sp(2)-sp(3) hybridized. C-H⋯π inter-actions involving the furan and benzene rings are found in the crystal structure.
在标题化合物C₂₂H₂₈O₃中，苯环之间的二面角为3.47 (13)°，五元呋喃环基本呈平面状，最大偏差为0.0052 (14) Å。两个苯环之间的Csp²-Csp²键长[1.443 (3) Å]明显短于苯环与叔碳（均为sp²-sp³杂化）之间的键长[1.538 (3)和1.530 (3) Å]。晶体结构中存在涉及呋喃环和苯环的C-H⋯π相互作用。
