Dysprosium(III) bromide is an inorganic compound of bromine and dysprosium, with the chemical formula of DyBr₃.

Preparation edit

Dysprosium(III) bromide can be obtained by reacting dysprosium with bromine:^[4]

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.^[1]

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:^[5]

Dy₂O₃ + Al₂Br₆ → Al₂O₃ + 2 DyBr₃

Properties edit

Dysprosium(III) bromide is a white-gray hygroscopic solid that is soluble in water.^[6] It has a trigonal crystal structure of the bismuth(III) iodide type with space group R3 (No. 148).^[7]
