title: 7-Hy-droxy-4-methyl-8-(3-methyl-benzo-yl)-2H-chromen-2-one ethanol monosolvate.
abstract: In the title compound, C(18)H(14)O(4)·C(2)H(6)O, 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, mol-ecules are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions.
