三溴化钚是一种无机化合物，化学式为PuBr₃，存在无水物和水合物。无水物和水合物在放置时会因为钚的α辐射而分解。^[4]

制备及性质

三溴化钚可由二氧化钚和溴化氢或和一氧化碳和溴在650~800 °C反应得到；也可由钚的草酸盐（Pu₂(C₂O₄)₃·9H₂O或Pu(C₂O₄)₂·6H₂O）在500 °C和溴化氢反应得到。^[4]^[5]

{\ce {2 PuO2 . x H2O + 8 HBr -> 2 PuBr3 + (4 + 2 x) H2O + Br2}}

{\ce {Pu2(C2O4)3 . 10 H2O + 6 HBr -> 2 PuBr3 + 3 CO + 3 CO2 + 13 H2O}}

三溴化钚六水合物可从溶液中结晶得到。^[2]

它和三氧化二锑在真空中加热反应，可以得到PuOBr。^[6]它和K₂COT在THF中于−10~−20 °C反应，可以得到KPu(COT)₂·2THF。^[7]
