Superconducting, metal-doped fullerenes are provided, along with processes for their preparation in relatively high stoichiometric purity. In one embodiment, the processes provide fullerenes of the formula M.sub.x C.sub.q, where M is a metal, x is greater than 0 but less than about 10, and q is at least 60. The processes comprise contacting C.sub.q with metal in an amount and under reaction conditions effective to produce a compound having the formula M.sub.y C.sub.q, and contacting said M.sub.y C.sub.q with a portion of C.sub.q in an amount and under reaction conditions effective to produce said M.sub.x C.sub.q, wherein y is greater than x.
A process for preparing a compound having the formula M.sub.3 C.sub.60, comprising the steps of:
A process for preparing a compound having the formula M.sub.x C.sub.60 where M is metal and x is greater than 0 and less than about 10, comprising the steps of:
A process for preparing a compound having the formula M.sub.x C.sub.q where M is metal, x is greater than 0 and less than about 10, and q is greater than about 60, comprising the steps of:
