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]
