| 摘要: 以三(2-巯吡啶基)甲烷(L)为配体合成了2个Cd(Ⅱ)和Zn(Ⅱ)的配合物:Cd(L)4(NO3)2和Zn(L)4(ClO4)2,发现在配合物中配体的C-S键发生了断裂,通过紫外、质谱手段研究并预测了其反应机理。单晶X-射线衍射的结果显示,配合物1和2中金属原子均处于扭曲的四面体配位环境中,分子间π-π堆积作用将配合物1的分子结构延伸为二维网状结构。 |

| Abstract: Two complexes of Cd(Ⅱ) or Zn(Ⅱ) with L (L=tris(2-mercaptopyridyl)methane), Cd(L)4(NO3)2 (1) and Zn(L)4(ClO4)2 (2), have been synthesized and characterized. The cleavage of the C-S bonds of the ligand has been discovered and the cleavage mechanism has been studied by UV-Vis titration and GC-MS. The possible reaction mechanism has been proposed. Single crystal X-ray analyses show that the Cd and Zn atoms are all in a four-coordinated distorted tetrahedron environment. The intermolecular π-π stacking action extends the complex 1 to a 2D net work. CCDC: 627210, 1; 644051, 2. |
