Chemical compoundTemplat:SHORTDESC:Chemical compound

Prometium(III) bromida adalah sebuah senyawa anorganik radioaktif dengan rumus PmBr₃. Senyawa ini adalah kristal dari sistem kristal heksagonal, dengan grup ruang P6₃/mc (No. 176).

Pembuatan

Prometium(III) bromida dapat diperoleh dengan mereaksikan hidrogen bromida dan prometium(III) oksida:^[2]

Pm₂O₃ + 6 HBr —^500°C→ 2 PmBr₃ + 3 H₂O

Prometium(III) bromida hidrat tidak dapat dipanaskan untuk membentuk anhidrat. Sebaliknya, ia terurai dalam air untuk membentuk prometium oksibromida:^[3]

PmBr₃ + H₂O(g) → PmOBr + 2 HBr
