Our work in the area of carbon-monoxide-releasing molecules led to the synthesis and crystallization of new flavone derivatives as intermediates. Herein we report the first crystal structure of the title compound, C16H12O3, a hydroxy-substituted flavone where the 2-phenyl group has been replaced by a p-tolyl group. The introduction of the 3-hydroxy group allows the formation of intermolecular O—H...O=C hydrogen bonds, used to build centrosymmetric R22(10) ring motifs in the crystal.
