metalliioon
Metalliioon is a hypothetical concept in inorganic chemistry referring to a metal-derived ion with an exceptionally high positive charge. Unlike conventional metal ions such as Fe3+ or Al3+, metalliions are proposed to exist only under special conditions or within theoretical models, where extreme ligand fields or confinement stabilize unusually high oxidation states. The term is not an official IUPAC designation and is largely found in speculative discussions rather than in established experimental literature.
In theoretical work, metalliions are envisaged as species formed when a metal center interacts with highly
Predicted properties include high electrophilicity, strong oxidizing or reducing capabilities depending on the surrounding medium, and
Applications remain speculative; potential areas include catalysis involving multi-electron transfer, advanced materials research, or energy storage
