RESUMEN
In the title compound, C20H18O4, the dihedral angle between the 2H-chromen-2-one ring system and the phenyl ring is 89.12â (5)°. In the crystal, the mol-ecules are connected through C-Hâ¯O hydrogen bonds to generate [010] double chains that are reinforced by weak aromatic π-π stacking inter-actions. The unit-cell packing can be described as a tilted herringbone motif. The Hâ¯H, Hâ¯O/Oâ¯H, Hâ¯C/Câ¯H and Câ¯C contacts contribute 46.7, 24.2, 16.7 and 7.6%, respectively, to its Hirshfeld surface.
