    Abstract: Several ions of (Formula presented.) rings in viewpoint of diatropic situation (aromatic) and also paratropic position (anti-aromatic) have been studied. 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.
