Vanadium(V) oxytrifluoride is a chemical compound with the formula VOF₃. It is one of several vanadium(V) oxyhalides. VOF₃ is a yellowish orange powder that is sensitive to moisture.{{cite book|last=Perry|first=Dale L.|title=Handbook of Inorganic Compounds|publisher=CRC Press|year=2011|isbn=978-1-4398-1461-1}} Characteristic of early metal fluorides, the structure is polymeric in the solid state. The solid adopts a layered structure but upon evaporation, the species becomes dimeric. In contrast VOCl₃ and VOBr₃ remain tetrahedral in all states, being volatile liquids at room temperature.Holleman, A. F.; Wiberg, E.
