The asymmetric unit of the title compound, C(18)H(16)Cl(4)N(2)O(2), comprises half of a potentially tetra-dentate Schiff base ligand. It is located about a twofold rotation axis that bis-ects the central C-C bond of the butane-1,4-diamine group. There are two intra-molecular O-H⋯N hydrogen bonds making S(6) ring motifs. In the crystal, mol-ecules are linked by pairs of weak C-H⋯Cl inter-actions, forming inversion dimers, which are further connected by C-H⋯O hydrogen bonds into two-dimensional frameworks that lie parallel to (001).
标题化合物C(18)H(16)Cl(4)N(2)O(2)的不对称单元包含一个潜在的四齿席夫碱配体的一半。它位于一个二重旋转轴上，该轴平分丁烷-1,4-二胺基团的中心C-C键。存在两个分子内O-H⋯N氢键，形成S(6)环模式。在晶体中，分子通过成对的弱C-H⋯Cl相互作用连接，形成反演二聚体，这些二聚体通过C-H⋯O氢键进一步连接成平行于(001)的二维框架。
