In the title compound, [Co(C(4)H(7)N(2)O(2))Cl(2)(C(4)H(8)N(2)O(2))], the Co(III) ion has a distorted octa-hedral coordination environment. The equatorial plane consists of four N atoms, two each from the dimethyl-glyoxime and dimethyl-glyoximate ligands, while the two axial positions are occupied by two chloride ions. Strong intra-molecular O-H⋯O hydrogen bonds are observed between the dimethyl-glyoxime and dimethyl-glyoximate ligands. Mol-ecules are linked into a chain running along the [101] direction by O-H⋯O and C-H⋯Cl hydrogen bonds. The chains are cross-linked through inter-molecular C-H⋯Cl hydrogen bonds.
在标题化合物[Co(C₄H₇N₂O₂)Cl₂(C₄H₈N₂O₂)]中，Co(III)离子具有扭曲的八面体配位环境。赤道平面由四个N原子组成，分别来自两个二甲基乙二肟和二甲基乙二肟酸根配体各两个，而两个轴向位置由两个氯离子占据。在二甲基乙二肟和二甲基乙二肟酸根配体之间观察到强的分子内O-H⋯O氢键。分子通过O-H⋯O和C-H⋯Cl氢键连接成沿[101]方向延伸的链。这些链通过分子间C-H⋯Cl氢键交联。
