The dinuclear title complex, [Cu(2)(C(46)H(38)N(4)O(2))Cl(2)]·0.5C(2)H(5)OH·2H(2)O, is located on crystallographic inversion centres with two half-mol-ecules in the asymmetric unit. The two Cu(II) atoms are coordinated by a hexa-dentate dianionic ligand formed in situ from the condensation of two tridentate ligands by four imine N atoms and two bridging phenolate O atoms along with two Cl atoms at axial positions. The coordination geometry around the metal atoms is distorted square-pyramidal (τ = 0.185 and 0.199). The non-bonding Cu⋯Cu distances are 2.9556 (12) and 2.9506 (12) Å in the two dimers. The packing is stabilized through solvent-mediated inter-molecular O-H⋯O and O-H⋯Cl hydrogen bonds. The diamine chain of one of the dimers is disordered over two positions in a 0.680 (5):0.320 (5) ratio.
双核标题配合物[Cu₂(C₄₆H₃₈N₄O₂)Cl₂]·0.5C₂H₅OH·2H₂O位于晶体学反演中心，不对称单元中有两个半分子。两个Cu(II)原子由一个六齿二价阴离子配体配位，该配体由两个三齿配体通过四个亚胺N原子和两个桥连酚盐O原子原位缩合而成，同时在轴向位置还有两个Cl原子。金属原子周围的配位几何形状为扭曲的四方锥（τ = 0.185和0.199）。在两个二聚体中，非键合的Cu⋯Cu距离分别为2.9556 (12) Å和2.9506 (12) Å。堆积通过溶剂介导的分子间O-H⋯O和O-H⋯Cl氢键得以稳定。其中一个二聚体的二胺链在两个位置上无序排列，比例为0.680 (5):0.320 (5)。
