Vanadium dioxide fluoride is the
inorganic compound with the formula VO2F. It is an orange diamagnetic solid. The compound adopts the same structure as
iron(III) fluoride, with octahedral metal centers and doubly
bridging oxide and fluoride
ligands. It is prepared by the reaction of vanadium pentoxide and
vanadium(V) oxytrifluoride:[1]
Like some other transition metal oxyfluorides, VO2F reacts with
Lewis bases to give 1:2 adducts. One example is the yellow bis(
pyridine) derivative VO2F(NC5H5)2.[2]
VO2F has attracted some interest as a cathode in batteries.[3]
