Endohedrally Zn and Zn2+ doped Si-60 structures, Zn@Si-60 and Zn2+@Si60, are considered for AM1 type semiempirical molecular orbital treatment at the restricted Hartree-Fock level. The calculations reveal that these structures should be stable but highly endothermic. The dopants, Zn and Zn2+, undergo some interactions with the Si-60 cage causing some geometry distortions and affecting the molecular orbitals.
