【摘要】 进行了系列异三核羧酸配合物〔Ｍ２Ｍ＇Ｏ（Ｏ２ＣＲ）６Ｐｙ３ 〕Ｘ （Ｍ， Ｍ＇ ＝ Ｃｒ， Ｆｅ，Ｍｎ； Ｒ＝ Ｈ， ＣＨ３， Ｃ２Ｈ５， Ｐｙ＝ 吡啶； Ｘ ＝ Ｏ２ＣＨ， Ｏ２ＣＥｔ， Ｃｌ， ＣｌＯ４）的快原子轰击质谱（ＦＡＢ－ＭＳ）研究， 观察到异三核的２ 类重组反应： 第１ 类生成含有〔Ｍ３〕和〔Ｍ２Ｍ＇〕两种碎片离子， 第２ 类则生成含有〔Ｍ３〕， 〔Ｍ２Ｍ＇〕， 〔ＭＭ＇２〕和〔Ｍ＇３〕等４ 种不同组合的碎片离子。文中初步探讨了进行２ 类重组反应的原因和规律。根据所提出的规律确定了金属离子反应速率的顺序为Ｃｒ ＞ Ｆｅ ＞ Ｍｎ。更多还原

【Abstract】 A series of heterotrinuclear carboxylato complexes 〔M 2M’O(O 2CR) 6Py 3〕X(M, M’=Cr, Fe, Mn; R=H, CH 3, C 2H 5; Py = pyridine; X = O 2CH, O 2CEt, Cl, ClO 4) are studied by the Fast Atom Bombardment Mass Spectra (FAB MS), and the results are reported in this paper. It has been found that there exist two kinds of recombination reaction of the trinuclear metals: the first forms two fragmentation ions 〔M 3〕 and 〔M 2M’〕, and the second forms four fragmentation ions, 〔M 3〕、 〔M 2M’〕、〔MM’ 2〕 and 〔M’ 3〕. The reason of the formation of this two kinds of recombination reaction as well as their regularity were discussed and the sequence of the reaction rate of metals has been concluded as: Cr > Fe > Mn.更多还原
