| Summary: | In the title compound, C19H16O4, there are two 4-hydroxybenzyl substituents on the oxan-4-one (tetrahydropyran-4-one) ring, which exhibits an envelope conformation. The dihedral angles between pyranone ring and the two benzene rings are 26.69 (9) and 36.01 (9)° while the benzene rings make a dihedral angle of 20.88 (10)°. In the crystal, molecules are linked by intermolecular O—H...O hydrogen bonds into a supramolecular three-dimensional twofold interpenetrating hydrogen-bonded network. |
