Calculation of hypothetical systems: Carbododecahedron (C20) and various diboracarbododecahedrons (B2C18) by the expanded Hückel method

Conclusions

  1. 1.

    The introduction of theΤ-system into the calculation of carbododecahedron does not change the character of the upper occupied levels, and consequently corroborates the previously obtained conclusion regarding the triplet character of the ground state of this molecule.

  2. 2.

    Within the framework of the EHM the various diboracarbododecahedrons have closed electron shells, which speaks in support of their possible existence.
