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

Abstract

The title compound, C15H13ClN2O 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 mol-ecules lie about inversion centers, forming dimers that are connected by inter-molecular O - H⋯N hydrogen bonds, resulting in six-membered rings with graph-set motif R 2 2(6). In addition, there is a strong inter-molecular O - H⋯N hydrogen-bonding inter-action, resulting in an S(6) ring motif. Weak π-π inter-actions between the benzene rings [centroid-centroid distance = 3.809 (1) Å] further stabilize the crystal structure.
