Abstract :
In the molecule of the title anthracene derivative, C22H17NO2, the benzene ring is inclined to the mean plane of the anthracene ring system (r.m.s. deviation = 0.024 Å) by 75.21 (9)°. In the crystal, molecules are linked by pairs of O—H⋯O hydrogen bonds, forming classical carboxylic acid inversion dimers with an R22(8) ring motif. The dimers are linked by C—H⋯π interactions, forming a supramolecular framework.
