'''三溴化钚'''是一种[[无机化合物]]，化学式为PuBr<sub>3</sub>，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。<ref name=Fomin>Fomin, V. V.; Reznikova, V. E.; Zaitseva, L. L. Preparation and some properties of plutonium tribromide. ''Zhurnal Neorganicheskoi Khimii'', 1958. 3: 2231-2235. ISSN: 0044-457X.</ref>

==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]]（Pu<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)<sub>3</sub>·9H<sub>2</sub>O或Pu(C<sub>2</sub>O<sub>4</sub>)<sub>2</sub>·6H<sub>2</sub>O）在500 °C和溴化氢反应得到。<ref name=Fomin /><ref>Georg Brauer (Hrsg.), unter Mitarbeit von Marianne Baudler u. a.: Handbuch der Präparativen Anorganischen Chemie. 3., umgearbeitete Auflage.
