摘要

摘要 合成了第一个基于不对称取代的 1,3-二酮(1,1,1-三氟-4-(2-甲氧基苯基)丁-2,4-二酮)的同金属二古巴烷镍(II)配合物,并利用同步辐射进行了 X 射线衍射研究(CCDC 编号 861889)。在该复合物的晶体中,镍原子连接成具有共同顶点的四面体,Ni...Ni 间距为 3.026-3.127 Å;通过羟基的氧原子的 μ3 桥接,该复合物的几何形状完成了扭曲的二古巴烷。每个金属中心的配位环境都是一个扭曲的八面体,配体被去质子化并具有双齿功能,形成六元螯合环。

The First Example of Dicubane Nickel(II) Complex in the Series of Unsymmetrically Substituted Diketones

The First Example of Dicubane Nickel(II) Complex in the Series of Unsymmetrically Substituted Diketones

The First Example of Dicubane Nickel(II) Complex in the Series of Unsymmetrically Substituted Diketones

The first homometal dicubane nickel(II) complex based on unsymmetrically substituted 1,3-diketone (1,1,1-trifluoro-4-(2-methoxyphenyl)butan-2,4-dione) was synthesized and studied by X-ray diffraction using synchrotron radiation (CCDC no. 861889). In the crystal of the complex, nickel atoms are joined into tetrahedra sharing a common vertex with Ni…Ni distances of 3.026–3.127 Å; the geometry is completed to a distorted dicubane by μ3-bridging oxygen atoms of the hydroxyl groups. The coordination environment of each metal center is a distorted octahedron, the ligand is deprotonated and performs a bidentate function, forming six-membered chelate rings.
