Dysprosium(III) fluoride is an inorganic compound of dysprosium with a chemical formula DyF3.

Contents

Production

Dysprosium(III) fluoride can be produced by mixing dysprosium(III) chloride or dysprosium(III) carbonate into 40% hydrofluoric acid. [1]

DyCl3 + 3 HF → DyF3 + 3 HCl
Dy2(CO3)3 + 6 HF → 2 DyF3 + 3 H2O + 3 CO2

DyF3 can also be produced by hydrothermal reaction of dysprosium nitrate and sodium tetrafluoroborate at 200 °C. [2]

DyF3 can also be produced when dysprosium oxide and ammonium bifluoride are mixed and heated to 300 °C until the oxide is porous, and continued to heat to 700 °C. When hydrogen fluoride is introduced, a reaction occurs: [3]

Dy2O3 + 6 HF → 2 DyF3 + 3 H2O

Properties

Dysprosium(III) fluoride is a white, odorless solid that is insoluble in water. [4] It has an orthorhombic crystal structure with the space group Pnma (space group no. 62). [5]

Dysprosium(III) chloride (DyCl3), also known as dysprosium trichloride, is a compound of dysprosium and chlorine. It is a white to yellow solid which rapidly absorbs water on exposure to moist air to form a hexahydrate, DyCl3·6H2O. Simple rapid heating of the hydrate causes partial hydrolysis to an oxychloride, DyOCl.

Terbium(IV) fluoride is an inorganic compound with a chemical formula TbF4. It is a white solid that is a strong oxidizer. It is also a strong fluorinating agent, emitting relatively pure atomic fluorine when heated, rather than the mixture of fluoride vapors emitted from cobalt(III) fluoride or cerium(IV) fluoride. It can be produced by the reaction between very pure terbium(III) fluoride and xenon difluoride, chlorine trifluoride or fluorine gas:

Praseodymium compounds are compounds formed by the lanthanide metal praseodymium (Pr). In these compounds, praseodymium generally exhibits the +3 oxidation state, such as PrCl3, Pr(NO3)3 and Pr(CH3COO)3. However, compounds with praseodymium in the +2 and +4 oxidation states, and unlike other lanthanides, the +5 oxidation state, are also known.

Neodymium(III) carbonate is an inorganic compound, a salt, where neodymium is in the +3 oxidation state and the carbonate ion is in the -2 oxidation state. It has a chemical formula of Nd2(CO3)3. The anhydrous form is purple-red, while the octahydrate is a pink solid. Both of these salts are insoluble in water.

Praseodymium(III) carbonate is an inorganic compound, with a chemical formula of Pr2(CO3)3. The anhydrous form is olive green, and many of its hydrates such as heptahydrate and octahydrate are known. They are all insoluble in water.

<span class="mw-page-title-main">Europium compounds</span> Compounds with at least one europium atom

Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl3, Eu(NO3)3 and Eu(CH3COO)3. Compounds with europium in the +2 oxidation state are also known. The +2 ion of europium is the most stable divalent ion of lanthanide metals in aqueous solution. Many europium compounds fluoresce under ultraviolet light due to the excitation of electrons to higher energy levels. Lipophilic europium complexes often feature acetylacetonate-like ligands, e.g., Eufod.

Terbium compounds are compounds formed by the lanthanide metal terbium (Tb). Terbium generally exhibits the +3 oxidation state in these compounds, such as in TbCl3, Tb(NO3)3 and Tb(CH3COO)3. Compounds with terbium in the +4 oxidation state are also known, such as TbO2 and BaTbF6. Terbium can also form compounds in the 0, +1 and +2 oxidation states.

Erbium compounds are compounds containing the element erbium (Er). These compounds are usually dominated by erbium in the +3 oxidation state, although the +2, +1 and 0 oxidation states have also been reported.

Lutetium compounds are compounds formed by the lanthanide metal lutetium (Lu). In these compounds, lutetium generally exhibits the +3 oxidation state, such as LuCl3, Lu2O3 and Lu2(SO4)3. Aqueous solutions of most lutetium salts are colorless and form white crystalline solids upon drying, with the common exception of the iodide. The soluble salts, such as nitrate, sulfate and acetate form hydrates upon crystallization. The oxide, hydroxide, fluoride, carbonate, phosphate and oxalate are insoluble in water.
