Шаблон:Chembox Dysprosium(III) bromide is an inorganic compound of bromine and dysprosium, with the chemical formula of DyBr3.
Preparation
Dysprosium(III) bromide can be obtained by reacting dysprosium with bromine:[1]
- 2Dy + 3Br2 → 2DyBr3
Dysprosium bromide hexahydrate can be obtained by crystallization from its solution,[2] which can be heated with ammonium bromide in vacuum to obtain the anhydrous form.[3]
Dysprosium(III) oxide and aluminium bromide (in the form of Al2Br6 at a high temperature react a DyAl3Br12, which decomposes to dysprosium(III) bromide at a lower temperature:[4]
- Dy2O3 + Al2Br6 → Al2O3 + 2 DyBr3
Properties
Dysprosium(III) bromide is a white-gray hygroscopic solid that is soluble in water.[5] It has a trigonal crystal structure of the bismuth(III) iodide type with space group R3 (No. 148).[6]
