V3O93
V3O93 is a formula that has appeared in some informal or stray sources as a vanadium oxide, but it is not recognized as a valid or stable compound in authoritative chemical databases or mineral dictionaries. The empirical composition implied by V3O93 would require three vanadium atoms combined with ninety-three oxide ions.
Chemical viability and interpretation
To be electrically neutral as an oxide, the total positive charge from vanadium would have to balance
Possible explanations for the notation
If V3O93 appears in a text or database, it is likely a typographical error or a misinterpretation
Vanadium oxides (such as V2O5, VO2, V2O3), nonstoichiometric oxide materials, vanadium chemistry, oxide minerals. Further references
