【摘要】 通过电子轰击谱,并借助亚稳技术及同位素丰度的比较分析,提出了（Et₄N）(MoFe₃S₄（Et₂dtc）-6]·CH₃CN质谱的可能断裂形式指出谱中的三个特征峰m/z 586、500及352的元素组成分别为MoFeS₆C₁₄H₃₀N₃,FeS₈C₁₅H₃₀N₃和FeS₄C₁₄H₂₀N₂₀m/z352的母离子为m/z500,而其子离子为m/z288、276和204。并由这些离子继续裂解成一系列较小的碎片离子。更多还原

【Abstract】 The mass spectra of the cubane-like compound(Et4N)CM0Fe3S4(Et2dtc)5]-CH3CN are studied by metastable technic and the calculation of isotope abundance. Further, we propose the mechanism of fragmentation and rearrangement of cubane-like compound, (Et4N) [MoFe3S4(Et2dtc)5]·CH3CN, and inerpret the origins of three characteristic peaks m/z 586, 500 and 352.更多还原
