ENDOHEDRAL AND EXOHEDRAL ELECTRONIC INTERACTIONS BETWEEN METALS AND GIANT FULLERENE CAGES
Publisher:
Ohio State UniversityAbstract:
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 $U(C_{3}H_{3})_{2}$.
