title: 2-[N-(4-{4-[(E)-(2-Hydroxybenzyl-idene)amino]phenoxy}phenyl)carbox-imidoyl]phenol.
abstract: The mol-ecular structure of the title Schiff base compound, C(26)H(20)N(2)O(3), shows that respective methyl-idene residues are almost coplanar with the adjacent terminal benzene ring owing to the presence of intra-molecular 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 methyl-idene 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.
