4,4',6,6'-Tetrachloro-2,2'-[(1E,1'E)-propane-1,3-diylbis(nitrilomethanylylidene)]diphenol.

The title compound, C17H14Cl4N2O2, is generated by crystallographic twofold symmetry. The two benzene rings are inclined to one another by 80.17 (10)°. There are two intramolecular O-H...N hydrogen bonds, which make S(6) ring motifs. In the crystal, molecules are linked by C-H...O and weak C-H...Cl interactions, forming a three-dimensional network
