چکیده
In the title compound, C21H16O, the dihedral angle between the anthracene ring system and the benzene ring is 74.3 (5)°. The anthracene ring system is essentially planar (r.m.s. deviation = 0.0257 Å) and the meth-oxy group lies in the plane of the benzene ring [C1-O1-C2-C7 torsion angle = 0.5 (2)°]. The crystal structure features π-π [centroid-centroid distance = 3.9487 (12) Å] and C-H⋯π inter-actions, forming a sheet running along the a-axis direction.

The title compound, C(22)H(17)NO, is a novel Schiff base synthesized via a condensation reaction between 9-anthracenecarboxaldehyde and 2-amino-p-cresol. The asymmetric unit contains two independent mol-ecules that are joined by an O-H⋯OH hydrogen bond. An intra-molecular O-H⋯N hydrogen bond occurs in each mol-ecule. π-stacking about inversion centers was observed between adjacent phenol rings ...
