In this chapter, we review the preparation, separation, and characterization of a new family of trimetallic nitride template (TNT) endohedral metallofullerenes AnB3−nN@C2x (n = 0–3, x = 34, 39, and 40) where A and B are metals (Group III and rare earths) that are formed in relatively high yields. The archetypal representative of this new class is the stable endohedral metallofullerene, Sc3N@C80 containing a triscandium nitride cluster encapsulated in an icosahedron (Ih), C80 cage. Other prominent TNT members are Sc3N@C68 and Sc3N@C78. The former Sc3N@C68 molecule represents an exception to the well known isolated pentagon rule (IPR). |
