(2E)-3-(2-Anthracen-2-yl)-1-(2-hydroxyphenyl)prop-2-en-1-one

Abstract

The asymmetric unit of the title compound, C23H16O2, contains two independent molecules in which the dihedral angles between the anthracene ring system and the benzene ring are 73.0 (3) and 73.3 (3)°. In both independent molecules, the hydroxy group is involved in an intramolecular O—H...O hydrogen bond. The crystal packing is stabilized by π–π interactions [centroid–centroid distances = 3.6518 (9), 3.7070 (9) and 3.7632 (9) Å] and weak intermolecular C—H...O hydrogen bonds.
