Abstract
In the title compound, C27H24O14, also known as 2,3-diacetoxy-5-[(2RS,3RS)-3,5,7-triacetoxy-4-oxochromen-2-yl]phenyl acetate, the heterocyclic ring adopts a distorted half-chair conformation, with two C atoms displaced by 0.1775 (16) and −0.5950 (16) Å from the mean plane of the other four atoms. The dihedral angle between the aromatic rings is 57.81 (8)°. In the crystal, the molecules interact by C—H⋯O bonds, aromatic π–π stacking [centroid–centroid separation = 3.6206 (9) Å] and C—H⋯π interactions.
