【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。更多还原

【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.更多还原
