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

Abstract

The asymmetric unit of the title compound, C23H 16O2, 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 hy-droxy group is involved in an intra-molecular 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.
