The asymmetric unit of the title compound, C18H16Cl4N2O2, comprises half of a potentially tetra­dentate Schiff base ligand. It is located about a twofold rotation axis that bis­ects the central C—C bond of the butane-1,4-diamine group. There are two intra­molecular O—H⋯N hydrogen bonds making S(6) ring motifs. In the crystal, mol­ecules are linked by pairs of weak C—H⋯Cl inter­actions, forming inversion dimers, which are further connected by C—H⋯O hydrogen bonds into two-dimensional frameworks that lie parallel to (001).
