Halogenidioniins

Halogenidioniins are a theoretical class of chemical compounds that combine the properties of halogens and onium ions. In essence, they would be polyatomic cations or anions where at least one halogen atom is formally bound to a more electronegative element, carrying a positive or negative charge, respectively. For example, a hypothetical halogenidioniin might involve a positively charged species where a halogen atom is bonded to oxygen or nitrogen. Conversely, a negatively charged halogenidioniin could feature a halogen atom bonded to a more electropositive element, though this is less commonly considered.

The concept of halogenidioniins arises from extending the known chemistry of halogens and onium ions. While simple halogens like Cl-, Br-, or I- are well-established anions, and ions like ammonium (NH4+) or hydronium (H3O+) are common cations, halogenidioniins represent a more complex arrangement. Their stability and existence would depend heavily on the specific elements involved, their electronegativities, and the overall electronic structure of the species. Currently, no stable, experimentally verified halogenidioniins are widely recognized in mainstream chemical literature. Their existence remains largely within the realm of theoretical chemistry and speculation about novel bonding arrangements.
