Europium(III) bromide (or Europium tribromide) is a crystalline compound 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]
