I) produces a stabilizing effect on the doubly charged ions. A higher ion current is transported by doubly charged fragments of Mn(CO) 5 X with respect to Mn 2 (CO) 10 , while [M] 2+ accompanied by doubly charged high mass fragments are originated by Re(CO) 5 X. The strong increase of the relative abundances of doubly charged ions observed in the mass spectra of Fe 2 (CO) 6 C 4 (C 2 H 5 ) 4 and Os 2
摘要报道了单金属和双金属羰基化合物在40、70和100 eV电子束能量下在质谱中产生的双电荷离子。Fe 2(CO)9和Mn 2(CO)10给出非常弱的双电荷离子,而在Re 2(CO)10的质谱图中观察到这些种类的相对丰度却大大增加。Mn(CO)5 X和Re(CO)5 X(X = Cl,Br,I)中卤代配体的存在对双电荷离子产生稳定作用。相对于Mn 2(CO)10,较高电荷的Mn(CO)5 X的双电荷碎片传输离子,而由Re(CO)5 X引发的[M] 2+伴随双电荷的高质量碎片离子传输。
