Holmium(III) fluoride is an inorganic compound with a chemical formula of HoF3.
Holmium(III) fluoride can be produced by reacting holmium oxide and ammonium fluoride, then crystallising it from the ammonium salt formed in solution: [3]
It can also be prepared by directly reacting holmium with fluorine: [4]
Holmium(III) fluoride is a yellowish powder that is insoluble in water. [5] It has an orthorhombic crystal system (corresponding to β-YF3 [6]) with the space group Pnma (space group no. 62). [7] However, there is also a trigonal low-temperature form of the lanthanum(III) fluoride type. [3]
