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

Contents

Preparation

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

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]

Gold(III) bromide is a dark-red to black crystalline solid. It has the empirical formula AuBr3, but exists primarily as a dimer with the molecular formula Au2Br6 in which two gold atoms are bridged by two bromine atoms. It is commonly referred to as gold(III) bromide, gold tribromide, and rarely but traditionally auric bromide, and sometimes as digold hexabromide. As is similar with the other gold halides, this compound is unique for being a coordination complex of a group 11 transition metal that is stable in an oxidation state of +3 whereas copper or silver complexes persist in oxidation states of +1 or +2.
