2-[((E)-{2-[(E)-(2-Hydroxybenzylidene)amino]benzyl}imino)methyl]phenol

Abstract

In the title hydroxyphenyl-substituted salophene compound, C21H18N2O2, there are two intramolecular O—H...N hydrogen bonds forming S(6) ring motifs. The phenol rings are inclined to one another by 65.9 (3)°, and by 0.0 (2) and 65.9 (2)°, respectively, to the central benzene ring. In the crystal, molecules are linked by a weak C—H...O contact forming chains along [010].
