Abstract

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 [centroid-centroid distance = 3.850 (2) Å] and adjacent anthracene rings [centroid-centroid distance = 3.834 (2) Å]. The C-N=C-C torsion angles between the phenol and anthracene rings are close to 180° with values of 174.06 (15) and 179.85 (14)°.
