4,6-Dichloro-2-{[(E)-(3-{[(E)-3,5-dichloro-2-hy­droxy­benzyl­idene]amino}-2,2-dimethyl­prop­yl)imino]­meth­yl}phenol

In the title compound, C₁₉H₁₈Cl₄N₂O₂, a potential tetra­dentate Schiff base ligand, the dihedral angle between the two benzene rings is 48.01 (10)°. The configuration about the two C=N bonds is E and two intra­molecular O—H...N hydrogen bonds make S(6) ring motifs. In the crystal, mol­ecules are linked along the b axis via inter­molecular C—H...Cl inter­actions. The crystal structure is further stabilized by an inter­molecular π–π inter­action [centroid–centroid distance = 3.5744 (12) Å].
