“…[51,52] However, for the synthesis of CCMFs, the conventional direct current arc-discharge method is the the most popular one. [53,54] Under helium atmosphere, the metal oxides and carbon sources, including graphite and carbon tube, are vaporized by the Krätschmer-Huffman generator. To avoid degradation of CCMFs, the product soot is usually collected under anaerobic conditions.…”

“…After the high-performance liquid chromatography (HPLC) separation procedure, the purified CCMF is obtained (Figure 1). [54] If the compound can be successfully synthesized and separated experimentally, meaning that this compound has a certain stability. At present, the CCMF has been experimentally synthesized and isolated, mainly encaging transition metals (Sc, Ti, and Y) and lanthanide metals (La, Er, Gd, Tb, Dy, and Lu).…”

Since the discovery of the first carbide cluster metallofullerene (CCMF) Sc 2 C 2 @C 84 in 2001, CCMFs have attracted great concerns with variable structures and fascinating characteristics. To date, there are hundreds of studies on CCMFs. Crystallography studies on CCMFs are carried out by single-crystal X-ray diffraction. Theoretical calculations can also be used to study CCMFs in detail without being limited by low experimental yields. This review analyzes the stability of CCMFs reported previously, and indicates that the C 2 unit contributes a lot to their stability. At the same time, the relationship between the structures of inner carbide cluster and cage size is systematically discussed, and the four-electron transfer always occurs. Furthermore, the possible transformation rule between di-EMFs and CCMFs is indicated. Finally, an outlook regarding the future developments and applications of CCMFs is presented.
