In the crystalline state, the title molecule, C15H12O3, exists in the enolized form and displays a strong intramolecular hydrogen bond. The molecular structure supports the hypothesis that the conjugation in the molecule is a determining factor for the position of the enol H atom. The packing of the molecules shows interactions between phenyl H atoms and enol groups, thus forming weak C—H…O bonds. Possible C—H… interactions are also indicated.
