Is Fullerene C_(60) Large Enough to Host a Multiply Bonded Dimetal?

摘要

Some dimetal fullerenes M_2@C_(60) (M = Cr, Mo, W) have been studied with computational quantum chemistry methods. The transition metal diatomic molecules Cr_2, Mo_2, W_2 form exohedral complexes with C_(60), while U_2 forms a highly symmetric endohedral
