In the title complex, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(6)H(7)N)]·0.5H(2)O, the central Co(III) ion, chelated by four N atoms of the two bidenate glyoximate ligands, exhibits a slightly distorted octa-hedral geometry. The axial positions are occupied by a chloride ion and the 4-methyl-pyridine N atom. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules in the crystal via the water mol-ecules, while the glyoximate ligands exhibit intra-molecular O-H⋯O hydrogen bonds.
在标题配合物[Co(C₄H₇N₂O₂)₂Cl(C₆H₇N)]·0.5H₂O中,中心Co(III)离子被两个双齿乙二肟酸酯配体的四个N原子螯合,呈现出略微扭曲的八面体几何构型。轴向位置由一个氯离子和4-甲基吡啶N原子占据。分子间的O—H⋯O氢键通过水分子将晶体中的分子连接起来,而乙二肟酸酯配体则呈现出分子内的O—H⋯O氢键。
