摘要/Abstract

摘要： 用MASNMB方法考察了几种含=CuX(X=Cl,Br,I)的Mo-Cu-S双金属簇化合物晶体粉末样品。对所得¹³C共振峰进行了归属并讨论了=CuX配体对谱峰的影响。对三种簇合物(t-BuNC)₄Mo(t-BuS)₂,(t-BuNC)₄Mo(μ-t-BuS)₂CuX和(t-BuNC)₄Mo(μ-t-BuS)(μ-CO)CuX的晶体粉末¹³C谱进行了比较。提出了一种对微量粉末样品进行MASNMR研究的有效而简单的方法。

Abstract: Some powder samples of molybdemum-copper-sulpher dimetal cluster containing=CuX form ligands, where X represents halogen, were studied by MASNMR method. The lines obtained were assigned and the effects of=CuX ligands on the positions of various lines were discussed. Comparisons between the ¹³C spectra of three crystalline powder, (t-BuNC)₄ Mo(t-BuS)₂, (t-BuNC)₄ Mo (μ-t-BuS)₂CuX and (t-BuNC)₄ Mo(μ-t-BuS) (μ-CO)CuX, were made. A simple but successful way to perform an inves tigation when the powder sample to be studied was not sufficient was also proposed.
