The paper provides experimental data on the synthesis and study of the superconducting properties of potassium and rubidium heterofullerides modified by Wood’s alloy — Sn, Pb, Bi, Cd (hereinafter W) with a melting temperature T_m = 61.5 °C or Y alloy — Bi, Sn, Pb, In, Cd, Tl with T_m = 41.5 °C. The synthesis of heterofullerides was carried out by the interaction of fullerides of the composition K₂C₆₀ and Rb₂C₆₀, which do not have superconducting properties, with one of the alloys W or Y in an organic solvent — toluene at 100–110 °C. The samples obtained in this case showed superconducting properties with T_c = 8 K for K₂YC₆₀ and Rb₂WC₆₀ and 16 K for K₂WC₆₀.
