In the racemic title compound, C 21 H 18 O 4 , 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 inter­actions [minimum ring centroid separation = 3.9286 (17) Å].
