The title compound, C18H14O4, forms a supramolecular structure via pi-pi stacking and weak C - H ... O and C-H ...pi interactions. The benzopyran moiety is almost planar. The benzene ring of the phenylmethyl acetate substituent is nearly perpendicular to the fused benzene and pyran rings and also to the methyl acetate group.
