Abstract
We shell consider special metals with the right number of electrons to stay inside the carbon cages of the right symmetry or 10 replace the carbon on the surface. For fullerene $cages^{1.3}$ with subgroup of three-fold symmetry and three or six free $\pi$ electrons, we consider $C_{34}(C_{34}), C_{36}(C_{36}), C_{60}(C_{60}), C_{74}(C_{74}), C_{32}(C_{32})$ etc. For cages with subgroup of "four" -fold and two-fold symmetry we consider $C^{+}_{29}(C_{29}), C^{+}_{33}(C_{33}), C^{+}_{34}(C_{34}), C_{28}(T_{28}), C_{56}(T_{d}), C_{76}(T_{d})$ etc., some may also have four or eight free $\pi$ radical electrons. The metals with three electrons are $Sc, Y, La$, etc., with "four" electrons are $Ti, Zr, Hf, Th U$ etc. These will be compared with metallocenes $Cr(C_{6}H_{6})2, Fe(C_{5}H_{5})_{2}$ and $U(C_{3}H_{3})_{2}$.
