In the title compound, [Cd(CH3COO)2(C6H7N3O)2]·2C2H5OH, the Cd(II) atom, which lies on a twofold rotation axis, is coordinated by two monodentate acetate groups and two N,N'-chelating pyridine-2-carboxamide oxime ligands, leading to a distorted octahedral coordination sphere. The mononuclear complex mol-ecules are assembled into chains along the c-axis direction via N-H⋯O hydrogen-bonding inter-actions. These chains are further assembled by O-H⋯O hydrogen bonds involving the ethanol solvent mol-ecules into a three-dimensional supramolecular structure.
在标题化合物[Cd(CH₃COO)₂(C₆H₇N₃O)₂]·2C₂H₅OH中，位于二重旋转轴上的Cd(II)原子由两个单齿乙酸根基团和两个N,N'-螯合的吡啶-2-甲酰胺肟配体配位，形成一个扭曲的八面体配位环境。单核配合物分子通过N-H⋯O氢键相互作用沿c轴方向组装成链。这些链通过涉及乙醇溶剂分子的O-H⋯O氢键进一步组装成三维超分子结构。
