A mixed actinide–lanthanide cluster fullerene, Sc₂UC@I_h(7)-C₈₀, was isolated and fully characterized. For the first time, the single crystal X-ray crystallographic analysis confirms a novel actinide–lanthanide cluster Sc₂UC stabilized inside an I_h(7)-C₈₀ cage. Moreover, the UC double bond distance is 2.01 Å, the shortest UC bond confirmed by crystallography so far.
