Abstract

In the title compound, C15H14O2, the dihedral angle between the two aromatic rings is 87.98 (13)°. The primary interaction is an intramolecular O—H...O=C interaction [O...O = 2.559 (3) Å]. Intermolecular interactions/contacts are weak and are of the O—H...C, C—H...π(arene) and π–π(arene) types [ Cg... Cg( ) = 3.927 (1) Å; Cg is the centroid of the phenyl ring]. [ABSTRACT FROM AUTHOR]
