Abstract
Using density functional theory, the structure and electronic properties of TM@C20 (TM = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) complexes were investigated. The study revealed that the doping processes of Sc, Ti, V, Cr, Mn, and Fe atoms at the center of C20 fullerene are exothermic and those of Co, Ni, Cu, and Zn atoms are endothermic. In addition, the endohedral complexation with Sc, Ti, V, Cr, Mn, and Fe atoms significantly influence the electronic properties of the C20 clusters. The calculated vibrational frequencies for the Ti, V, and Mn complexes were positive, confirming the complexes are stable and can stabilize the unstable C20 fullerene with I h symmetry. The present results reveal details for the synthesis and structuring of C20 fullerene doped with Ti, V, and Mn and serves for the further developments of C20-based particles to generate new hybrid compounds.
