Europium(III) bromide (or europium tribromide) is a crystalline compound, a salt, made of one europium and three bromine atoms. [2] Europium tribromide is a grey powder at room temperature. [2] It is odorless. [5] Europium tribromide is hygroscopic. [6]

Reactions

When vaporized, europium(III) bromide reacts by the equation:

2 EuBr3 → 2 Eu + 3 Br2 [3] [7]

Europium(III) bromide is also created through the equations:

4 EuBr2 + 4 HBr → 4 EuBr3 + 2 H2 [7]
