在金属富勒烯盐Ｃ６０Ｍｘ（Ｍ＝Ｓｍ，Ｐｔ，Ｎｉ，Ｒｈ）的激光烧蚀飞行时间质谱研究中，观察到正负离子通道中有金属富勒烯Ｃ２ｎＭ与Ｃ２ｎ＋１Ｍ的形成．金属富勒烯的谱峰强度与根据碳原子与金属原子的同位素分布计算所得到的理论谱相一致，证实了金属富勒烯的形成．实验表明金属原子取代了碳笼上的一个碳原子而形成取代型金属富勒烯．同时，在激光烧蚀金属富勒烯盐的负离子通道中观察到奇数碳笼团簇的产生．激光烧蚀产物随激光轰击次数演变的实验表明，金属富勒烯的形成与金属碳化物ＭＣ的产生密切相关．在对奇数碳笼团簇结构优化计算的基础上，对金属富勒烯团簇Ｃ２ｎ＋１Ｍ与Ｃ２ｎＭ的结构特性以及形成机理进行了讨论．
In the laser ablation time-of-flight mass spectrometry study of the metal fullerene C60Mx (M = Sm, Pt, Ni, Rh), the formation of metal fullerenes C2nM and C2n + 1M in the positive and negative ion channels was observed. The peak intensities of the metal fullerenes coincide with the theoretical spectra calculated from the isotopic distribution of carbon atoms to metal atoms, confirming the formation of metal fullerenes. Experiments show that a metal atom replaces a carbon atom on a carbon cage to form a substituted metal fullerene. At the same time, odd-numbered carbon cage clusters were observed in the negative ion channels of laser-ablated metal fullerene salts. Experiments on the evolution of laser ablation products with laser bombardment times show that the formation of metal fullerenes is closely related to the formation of metal carbides MC. Based on the optimization calculation of the odd-numbered carbon cage structure, the structural properties and formation mechanism of C2n + 1M and C2nM fullerene clusters are discussed.
