Abstract
In the title compound, C18H14O4·C2H6O, the coumarin ring system is approximately planar with a maximum deviation of 0.037 (3) Å and is nearly perpendicular to the benzene ring, making a dihedral angle of 86.55 (9)°. In the crystal, molecules are linked by classical O—H⋯O hydrogen bonds and weak C—H⋯O interactions.
