“…[282] Examples of transition metal doped fullerides are less abundant, and are summarised in Table 7. Among the transition metals fulleride compounds most common are smaller first row transition metals derivatives, with various examples of Cr compounds [285][286][287][288][289][290][291][292][293][294][295] as well as Ti, [283] V, [284] Mn, [296] Ni, [296,297] Fe [296,297] and Cu. [297] A few examples of larger second row transition metals such as Mo, [295,298] Pd, [299] Ag [297] and Cd [296], Pt [299][300][301] and Au [302] of the third row have also been reported.…”

“…23,24 Diffraction patterns of Na n C 60 ͑n=2,3͒ sodium fullerides synthesized by suspension of the metal in toluene 9,10,16,25 and from amalgams are shown in Figs. This is contrasted with the results for gaseous phase synthesis of the homofullerides, for which crystallographic data in the ICDD data base are taken as a standard.…”

“…At the same time, in samples with an assumed composition of K 2 TlC 60 and Rb 2 TlC 60 obtained by an exchange reaction of the alkali metal fulleride with TlCl in an organic solvent, 9,10,16 metallic thallium is determined uniquely. The T c for the substances obtained in this way are somewhat lower than for "standard" samples of gaseous-phase synthesized K 3 TlC 60 and Rb 3 TlC 60 , 17 and 27.2 K, respectively.…”

Communication: Molecular dynamics simulations of the interfacial structure of alkali metal fluoride solutions Intercalation of heavy alkali metals (K, Rb and Cs) in the bundles of single wall nanotubes AIP Conf.Liquid alloys of metals with mercury ͑amalgams͒ are used to synthesize the fullerides A n Hg x C 60 ͑A=K,Rb,Cs; n =2;3; x Ͻ 1͒, A n Tl m Hg x C 60 ͑A=K,Rb,Cs; n =1;2; m = 0.25-2; x Ͻ 1͒, and Na n C 60 ͑n=2,3͒. The samples are studied by x-ray diffraction, nuclear magnetic resonance, electron paramagnetic resonance, Raman scattering, and differential scanning calorimetry. The Na n C 60 ͑n=2,3͒ fullerides are not superconducting. Structural phase transitions are observed in them as the temperature is varied. K 2 Hg x C 60 is a superconductor with a transition temperature T c = 22 K, while K 3 Hg x C 60 is not superconducting. Rb n Hg x C 60 ͑n=2,3͒ are superconductors with T c = 24-25 K. The cesium fullerides with an assumed composition of Cs n Hg x C 60 ͑n=1-3͒ are either polymers ͑n=2,3͒ or crystallize in a rhombic lattice, but none are superconducting. A maximum T c = 22 K is observed in the K 2 Tl m Hg x C 60 fulleride with a thallium concentration m = 0.5. Cs n Tl m Hg x C 60 ͑n=1-3; m=1,2͒ is not superconducting, but KCsTlC 60 produced by means of exchange reactions with TlCl is a superconductor with T c = 21.7 K.
