【Abstract】 The ¹H NMR spectra have been determined for several single cubane-like cluster compounds MFe₃S₄（R₂NCS₂）₅(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.更多还原
