2-[N-(4-{4-[(E)-(2-Hydroxybenzyl­idene)amino]phenoxy}phenyl)carbox­imidoyl]phenol

摘要

The mol­ecular structure of the title Schiff base compound, C26H20N2O3, shows that respective methyl­idene residues are almost coplanar with the adjacent terminal benzene ring owing to the presence of intra­molecular O—H⋯N hydrogen bonds [the N—C—C—C torsion angles are −6.6 (7) and −6.7 (7)°]. However, twists are exhibited about each methyl­idene and respective benzene ring connected to the central O atom; the dihedral angles formed between the two inner and two outer benzene rings are 54.6 (2) and 45.6 (3)°, respectively. The conformation about each of the C=N bonds [1.285 (5) and 1.295 (5) Å] is E. In the crystal, extensive C—H⋯π contacts involving all benzene rings results in the formation of layers in the ac plane.
