通过使用四臂八齿Schiff配体(H4L)与六水合硝酸钴反应,成功合成了Co(Ⅱ)席夫碱配合物C26H26N3O3Co.3H2O,并使用元素分析、IR光谱及单晶X射线衍射等方法对配合物进行了表征.结构分析表明,配合物中的配体通过3个分枝上的N和O原子与金属离子配位,形成扭曲的八面体几何构型,配体上未参与配位的分枝发生了水解,氨基发生了质子化,且配合物通过分子间氢键的弱相互作用沿晶体学a轴方向排列成1D链状结构. The Co (Ⅱ) Schiff base complex C26H26N3O3Co.3H2O was successfully synthesized by the reaction of four-arm octadentate Schiff ligand (H4L) with cobalt nitrate hexahydrate. Elemental analysis, IR and single crystal X-ray diffraction The complexes were characterized by structural analysis.The ligands in the complexes coordinated with the metal ions through the N and O atoms of the three branches to form a distorted octahedron geometry with no ligand coordination The amino groups were protonated, and the weak interaction of the complexes through the intermolecular hydrogen bonds was arranged along the a-axis of the crystallography in a 1D chain structure.
