FeIVO

FeIVO is a term used in theoretical discussions to denote a hypothetical inorganic compound with the formula FeIVO, comprising iron (Fe), iodine (I), vanadium (V), and oxygen (O). It has no widely accepted structure or validated synthesis.

In speculative models, FeIVO could be a mixed-valence oxide where iron and vanadium adopt multiple oxidation states within a single lattice, with iodine introduced as an interstitial or substituent species. The lack of experimental data means properties are uncertain; predicted features include potential redox activity, catalytic versatility, and possibly magnetic behavior typical of transition-metal oxides.

Synthesis would require careful control of oxidation states and iodine content; proposed approaches could involve solid-state reactions of iron oxide and vanadium oxide with iodine sources at high temperature, or low-temperature routes incorporating iodide/iodate using strongly oxidizing environments. Stability may be challenged by iodine volatility and mobility.

Status and usage: The designation appears in limited theoretical discussions or speculative materials science proposals; it is not included in major chemical databases as of now.
