As noted above, the D3 symmetry does not provide the compounds with the required orbital degeneracy for 3D-aromaticity. Furthermore, in neutral 1, the dihedral angles between the tethers at the bridgehead atoms (δ1, δ2, and δ3, Figure ) are 26°, 46°, and 48°, which reveals that only one of the three cyclic paths is significantly -conjugated over the two bridgeheads as the -orbital overlap between two p AOs scales as cos with  being the angle between the two AOs. Yet, with the other dihedral angles in that (aromatic) cycle being 154 -171°, its conjugation is also attenuated. It was earlier reported that when D3 symmetric there is an equal aromaticity in the three rings, giving 1 aromatic character that seemingly extends over the complete molecule. However, as concluded above, the equal extent of aromaticity in the three local rings is a necessary result of the symmetry-adapted electronic structure and is not due to 3D aromaticity. Thus, it is also not appropriately described as an aromaticity of global character.
