Abstract
In the crystal structure of the title compound, C20H16O5, the molecule assumes an E configuration with the benzene ring and chromenecarboxyl group located on opposite ends of the C=C double bond. The chromene ring system and benzene ring are oriented at a dihedral angle of 74.66 (12)°. Weak intermolecular C—H...O hydrogen bonding is present in the crystal structure.
