三氟化镅

三氟化镅是镅的一种氟化物，化学式 AmF₃。

制备

三氟化镅可以由镅(III)的水溶液和氟化物在弱酸中反应而成。

{\ce {Am^3+(aq) + 3 F^- (aq) -> AmF3 (s) v}}

它也可以由氢氧化镅(III)在 600–750 °C ，HF/O₂ 的 1:1混合气体中反应而成。[5]

{\ce {Am(OH)3 + 3 HF -> AmF3 + 3 H2O}}

三氟化镅是一种粉红色固体，熔点 1393 °C。[4]它是氟化镧结构的，晶格参数 a = 704.4 pm 和c = 722.5 pm。[6] 每个镅原子都被九个氟原子包围，形成三侧锥三角柱。

金属镅可以通过三氟化镅被金属钡还原而成。[7][8]

{\ce {2 AmF3 + 3 Ba -> 2 Am + 3 BaF2}}
