Europium(II) bromide is a crystalline compound of one europium atom and two bromine atoms. Europium(II) bromide is a white powder at room temperature, and odorless. Europium dibromide is hygroscopic.

Reactions

Europium(II) bromide is known to be involved in three reactions:

2 EuBr₃ + Eu → 3 EuBr₂ (requires a temperature of 800-900 °C)

2 EuBr₃ → 2 EuBr₂ + Br₂ (requires a temperature of 900-1000 °C)

Eu + HgBr₂ → EuBr₂ + Hg (requires a temperature of 700-800 °C)
