Importantly, the local -orbitals of the -conjugated linkers must be oriented radially outward if they are to interact with the local p orbitals at the vertex atoms. We have also analyzed such tetrahedral and cubic species through computations (Figure and vide infra). These species must have radial orientations of their π-orbitals similar to charged fullerenes C60 10+ and C20 2+ , which have been explored computationally and found to follow Hirsch's 2(n + 1) 2 rule as they are spherically aromatic. Yet, Hirsch's rule has a limitation as it seems applicable only to species with 50 -electrons or less. A further caveat with regard to the cubic species is that each of the faces has 4m -electrons (m ≠ n), meaning that these can be Hückel-antiaromatic.
