By this work, it has been exhibited that some of these ion rings presented planar and some others exhibit a quasi-planar structures, due to Jahn–Teller and pseudo Jahn–Teller effects. Via this effort, we demonstrated that the global aromaticity or global anti-aromaticity can be assigned on the 4n + 2 (or 4n) electron counting rule for either π- or σ-electrons in the planar structures. In addition, the structures of these ions have been discussed computationally and confirmed via comparisons of experimental photoelectron spectrophotometry.falsearomaticity | B clusters n | Jahn–Teller effect | pseudo‑Jahn–Teller effectAn Aromaticity Study of Localized and Non-Localized Orbitals in (Formula presented.), and (Formula presented.)
