I_h Symmetrical (4,6)-Fullerenes and Their Local Ring Aromaticity: A First Principle Study

Figure 1

The geometrical structures of the I_h C₁₂₀ (a), C₂₄₀ (b), C₃₆₀ (c), and C₄₈₀ (d) (4,6)-fullerenes with isolated four- and six-membered rings. The dashed triangles show the symmetrically unique fragments of the fullerenes with respect to the icosahedron.
