Abstract: In the racemic title compound, C16H14O3, the ring of the 4-hydroxybenzyl substituent group forms a dihedral angle of 80.12 (12)° with the benzene ring of the chromanone system. Two C atoms of the pyranone ring and the H atoms on the benzyl [alpha]-C atom are disordered over two sites, with site-occupation factors of 0.818 (8) and 0.182 (8). The crystal structure is stabilized by O-H...O hydrogen bonds, which form parallel one-dimensional zigzag chains down the c axis and are interconnected by both methine C-H...O hydrogen bonds and weak aromatic C-H...[pi] interactions, giving a sheet structure lying parallel to [011].
