2-(4-Bromophenyl)-2-oxoethyl anthracene-9-carboxylate

Abstract

In the title compound, C23H15BrO3, the anthracene ring system is essentially planar [maximum deviation = 0.29 (2) ] and makes a dihedral angle of 5.74 (8) with the mean plane of the bromo-substituted benzene ring. An intramolecular C - H?O hydrogen bond generates an S(9) ring motif. In the crystal, molecules are linked by C - H?O interactions, forming a two-dimensional network parallel to the ac plane. ?-? stacking interactions are observed between benzene rings [centroid-centroid distances = 3.5949 (14) and 3.5960 (13) ].
