Ethyl 2-[2-(4-oxo-4H-chromen-2-yl)phen­oxy]acetate

In the title flavonoid derivative, C19H16O5, the chromene portion is planar (r.m.s. deviation = 0.022 A) with the substituents lying closely to the same plane. The dihedral angle between its mean plane and that of the benzene ring is 4.9 (1)°. This planarity is due, in part, to the presence of a strong intra­molecular C—H⋯O hydrogen bond and to two weak C—H⋯O contacts. In the crystal, neighboring mol­ecules are linked by a C—H⋯O hydrogen bond and a C—H⋯π inter­action, forming chains along the a-axis direction.
