摘要：
The fullerides A(n)M(m)C(60) (A=K, Rb, Cs; M= Be, Mg; B, Al, Ga. In; n=1, 2; m=1, 2) have been synthesized by exchange reactions of alkali metal fullerides with metal chlorides (groups 2 and 13), by method using liquid alloys of metals with mercury (amalgams), and by thermal decomposition of aluminum hydride. The samples are studied by X-ray diffraction, nuclear magnetic resonance, electron paramagnetic resonance, Raman scattering, and differential scanning calorimetry. It was found that the fulleride K2GaC60 is superconductor with transition temperature T-c=22 K that exceeds T-c for K3C60 (19 K). Fullerides with In and B are not supercomductors. The fullerides with composition CsnHgxC60 (n=2;3) are not superconductors and crystallize in orthorhombic lattices.
