Characteristic

 

Vanadium(V) oxytrifluoride is a chemical compound with the formula VOF₃. It is one of several vanadium(V) oxyhalides. 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.
