Rac-7-Methyl-3-[(7-methyl-4-oxo-chro-man-3-yl)meth-yl]-4H-chromen-4-one.

ABSTRACT: 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].
