Fe3O4osiota
Fe3O4osiota is a hypothetical or theoretical chemical compound proposed to exist under specific conditions, likely related to the chemistry of iron oxides and osmium. The name suggests a structure incorporating iron in its +2 and +3 oxidation states (Fe3O4 is magnetite) and osmium. However, there is no widely recognized or experimentally verified substance with this exact designation in standard chemical literature.
Research into superheavy elements and their compounds, or exotic high-pressure/high-temperature synthesis, might explore such theoretical possibilities.
