In the title compound, [CuCl(2)(C(9)H(11)N(3)O)], the Cu(II) atom is in a distorted square-pyramidal CuCl(2)N(2)O coordination geometry. The tridentate acetohydrazide ligand chelates in a meridional fashion. The chloride ligand in the axial position forms a long Cu-Cl distance of 2.4892 (9) Å. In contrast, the Cu-Cl distance from the equatorial chloride ligand is much shorter [2.2110 (7) Å]. Inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds link the complexes into a three-dimensional network.

在标题化合物[CuCl₂(C₉H₁₁N₃O)]中，Cu(II)原子处于扭曲的四方锥CuCl₂N₂O配位几何构型。三齿乙酰肼配体以经式方式螯合。轴向位置的氯配体形成了2.4892 (9) Å的长Cu-Cl距离。相比之下，来自赤道面氯配体的Cu-Cl距离要短得多[2.2110 (7) Å]。分子间的N-H⋯Cl和C-H⋯Cl氢键将配合物连接成三维网络。
