Vanadium oxide

'''Vanadium oxide''' mainly refers to:

* Vanadium(II) oxide (vanadium monoxide), VO * Vanadium(III) oxide (vanadium sesquioxide ''or'' trioxide), V₂O₃ * Vanadium(IV) oxide (vanadium dioxide), VO₂ * Vanadium(V) oxide (vanadium pentoxide), V₂O₅

Various other distinct phases include:

* Phases with the general formula V_nO_2n+1 exist between V₂O₅ and VO₂. Examples of these phases include V₃O₇, V₄O₉ and V₆O₁₃.<ref name = "Wells">{{Wells5th}}</ref> * Phases with the general formula V_nO_2n−1 exist between VO₂ and V₂O₃.<ref name = "Wells"/> Called '''Magnéli phases''' for [http://www.iucr.org/iucr-top/people/magneli.htm Arne Magnéli],<ref name ="Greenwood">{{Greenwood&Earnshaw}}</ref> they are examples of crystallographic shear compounds based on the rutile structure.<ref name = "Wells"/> Examples of Magnéli phases include V₄O₇, V₅O₉, V₆O₁₁, V₇O₁₃ and V₈O₁₅. * V₃O₅ appears as the mineral oxyvanite.<ref>{{Cite web|url=https://www.mindat.org/min-39006.html|title = Oxyvanite}}</ref>

Many vanadium-oxygen phases are non-stoichiometric.<ref name ="Greenwood"/>
