在研究三核钼原子簇的过程中已经发现,具有双齿螯合功能的[S_2P(OEt)_2]~-配基既可作端基螯合配体,又可桥联两个金属原子,因此有利于金属原子簇的形成。利用这一配基,我们曾经合成出一个类立方烷型的四核钼原子簇化合物{Mo_4(μ_3—S)_3(μ_3—O)[S_2P(OEt)_2]_6}。随
In the study of the tri-nuclear molybdenum clusters, it has been found that [S_2P (OEt) _2] ~ - ligands with bidentate chelation functions as both terminal chelating ligands and bridges two metal atoms, It is therefore advantageous for the formation of clusters of metal atoms. Using this ligand, we have synthesized a cubic-type tetranuclear molybdenum cluster {Mo_4 (μ_3-S) _3 (μ_3-O) [S_2P (OEt) _2] _6}. With
