This direct method of metal oxyfluoride synthesis can also be applied to the preparation of other compounds such as FeOF8 and TIOF.9 10 

The product is air- and moisture-stable. Anal. Calcd. for InOF In, 76.6 F, 12.7. Found In, 76.8 F, 12.4. The observed density is 6.55 g./cc., whereas the calculated theoretical density from the crystallographic data is 6.64 g/cc. 

Indium(III) oxyfluoride is a white crystalline solid which is practically insoluble in all ordinary solvents. It is not hydrolyzed in water at room temperature over a period of 24 hours, and it can be recovered unchanged from boiling water after 1 hour. The pure product was found to decompose at 340°C. in air to yield indium(HI) oxide. It is stable to higher temperatures (1100°C.) under an inert atmosphere or in vacuum.
