摘要：

In the title compound, C20H18O4, the dihedral angle between the 2H-chromen-2-one ring system and the phenyl ring is 89.12 (5)degrees. In the crystal, the molecules are connected through C-H center dot center dot center dot O hydrogen bonds to generate [010] double chains that are reinforced by weak aromatic pi-pi stacking interactions. The unit-cell packing can be described as a tilted herringbone motif. The H center dot center dot center dot H, H center dot center dot center dot O/O center dot center dot center dot H, H center dot center dot center dot C/C center dot center dot center dot H and C center dot center dot center dot C contacts contribute 46.7, 24.2, 16.7 and 7.6%, respectively, to its Hirshfeld surface.
