In the title complex, [Cu(C(12)H(7)Cl(2)N(2)O)(2)], the Cu(II) center is tetra-coordinated by two phenolic O and two azomethine N atoms from two bidentate 4-chloro-2-[(2-chloro-3-pyrid-yl)imino-meth-yl]phenolate (L) ligands. In the crystal structure, the Cu(II) atom has a distorted square-planar coordination environment. The dihedral angles between the benzene and pyridyl rings are 54.39 (3) and 80.14 (4)°, indicating that the pyridine ring has a considerably weaker steric hindrance. The packing of the mol-ecule is controlled by C-H⋯π(Ph) inter-actions and short O⋯Cl inter-actions [3.196 (4) Å], linking the mol-ecules into a chain-like structure along the c axis.
在标题配合物[Cu(C₁₂H₇Cl₂N₂O)₂]中，Cu(II)中心由来自两个双齿4-氯-2-[(2-氯-3-吡啶基)亚氨基甲基]苯酚盐(L)配体的两个酚羟基O原子和两个甲亚胺N原子进行四配位。在晶体结构中，Cu(II)原子具有扭曲的平面正方形配位环境。苯环和吡啶环之间的二面角分别为54.39 (3)°和80.14 (4)°，表明吡啶环的空间位阻明显较弱。分子堆积由C-H⋯π(Ph)相互作用和短的O⋯Cl相互作用[3.196 (4) Å]控制，这些相互作用将分子沿c轴连接成链状结构。
