In the racemic title compound, C21H18O4, the chromone ring is essentially planar [maximum deviation from the least-squares plane = 0.026 (3) Å], with a dihedral angle of 78.18 (12)° between the benzene rings of the chromanone and chromenone moieties. In the crystal, there are weak π-π stacking inter-actions [minimum ring centroid separation = 3.9286 (17) Å].
在消旋标题化合物C₂₁H₁₈O₄中，色酮环基本呈平面状[与最小二乘平面的最大偏差 = 0.026 (3) Å]，色满酮和色烯酮部分的苯环之间的二面角为78.18 (12)°。在晶体中，存在弱的π-π堆积相互作用[最小环心间距 = 3.9286 (17) Å]。
