The bonding properties in this cluster are described as a new manifestation of three-dimensional surface aromaticity. Each Al4C fragment of the cube is formed by four bonds with three electron pairs, thus leading to a strong delocalization of the electrons. A phenomenological modeling using a three-dimensional Huckel scheme with fitted parameters to reproduce the energies from ab initio calculations revealed that the orbital scheme localized at one Al4C fragment possesses an orbital sextet with a large HOMO-LUMO gap.
