4-Chloro-2-((E)-{3-[1-(hydroxy­imino)eth­yl]phen­yl}imino­meth­yl)phenol

The title compound, C(15)H(13)ClN(2)O(2), adopts an E conformation with respect to the azomethine C=N bond. The aniline and phenol rings are almost coplanar, making a dihedral angle of 3.33 (2)°. In the crystal, the mol­ecules lie about inversion centers, forming dimers that are connected by inter­molecular O—H⋯N hydrogen bonds, resulting in six-membered rings with graph-set motif R (2) (2)(6). In addition, there is a strong inter­molecular O—H⋯N hydrogen-bonding inter­action, resulting in an S(6) ring motif. Weak π–π inter­actions between the benzene rings [centroid–centroid distance = 3.809 (1) Å] further stabilize the crystal structure.
