摘要
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) angstrom from the mean plane of the other four atoms. The dihedral angle between the aromatic rings is 57.81 (8)degrees. In the crystal, the molecules interact by C-H center dot center dot center dot O bonds, aromatic pi-pi stacking [centroid-centroid separation = 3.6206 (9) angstrom] and C-H center dot center dot center dot pi interactions.
