'''溴化锔'''是[[锔]]的[[溴化物]]，化学式CmBr<sub>3</sub>。由于所有[[锔的同位素]]都是人造的，溴化锔不存在于自然界。

== 制备==
溴化锔可以由[[氯化锔]]和[[溴化铵]]在 400–450&nbsp;°C 的[[氢气]]气氛下反应而成。<ref name=asprey/>

:<chem>CmCl3 + 3 NH4Br -> CmBr3 + 3 NH4Cl</chem>

它也可以由[[三氧化二锔]]和[[氢溴酸]]在 600&nbsp;°C下反应而成。<ref name=burns/>

== 性质==
溴化锔是一种由 Cm<sup>3+</sup>和 Br<sup>−</sup>组成的[[离子化合物]]，外观为无色固体。它是[[正交晶系]]的，空间群 Cmcm (No. 63)，[[晶格参数]] ''a''&nbsp;=&nbsp;405&nbsp;[[皮米|pm]]、''b''&nbsp;=&nbsp;1266&nbsp;pm 和''c''&nbsp;=&nbsp;912&nbsp;pm。<ref name=asprey>L. B. Asprey, T. K. Keenan, F. H. Kruse: ''Crystal Structures of the Trifluorides, Trichlorides, Tribromides, and Triiodides of Americium and Curium'', in: ''[[Inorg.
