Five significant kind of introductory structure of neutral
Ge12 cluster with high symmetry point are appeared in
figure 1. To decide the most minimal energy structure of unadulterated
Ge12 cluster, we chose 5 separate high symmetry
geometries: the D6h-symmetric hexagonal crystal (HP),
the D6d-symmetric hexagonal anti-prism (HAP),
D2d-symmetric bi-capped pentagonal prism (BPP),
immaculate icosahedrons (Ih) and Fullerene type
structures. We improved these underlying geometries at B3LYP/LANL2DZ ECP
level of theory.
