Lanthanum(III) oxyfluoride is an inorganic compound of lanthanum, fluorine, and oxygen with the chemical formula LaOF.[1][2]


Several methods of synthesizing LaOF are known:

2LaF3 + H2O → LaOF + 2HF
2LaF3 · 0.5H2O → LaOF + LaF3 + 2HF
La2O3 + LaF3 → 3LaOF

Physical properties

The compound forms colorless crystals.


The compound is used to produce thin films.[3][4]
