【摘要】 <正>在绝氧绝水条件下,[Et4N]2MS4(M=Mo,W),FcCl2和NaS2CNR2在DMF介质中反应,得到一系列单立烷化合物MFe3S4(S2CNR25.样品溶解于DMSO-d6中,作1H NMR变温测量.表1列出它们在室温结果.

【Abstract】 The 1H NMR spectra have been determined for several single cubane-like cluster compounds MFe3S4(R2NCS25(M=Mo,W; R2=Me2,Et2,C4H4,OC4H8,C5H10).The isotropic shifts at theα-H of the ligands attaching iron atoms in the cluster compounds,as well as their temperature dependencies which obey essentially the Curie Law, are observed.The ligand exchange reaction in the compounds was also described briefly.In addition the influence of the distances among the metals of MFe3S4 cores on the NMR spectra of the ligands is discussed.
