Americium(II) bromide
Americium(II) bromide, also known as americium dibromide, is a chemical compound of americium and bromine with the formula AmBr2. It is a solid, although its properties are not well-characterized due to the radioactivity of americium and the challenges associated with handling and studying it. It is expected to be a reddish or brownish compound, analogous to other actinide dibromides. Synthesis typically involves the reduction of americium(III) bromide with a reducing agent or by thermal decomposition under vacuum. Its crystal structure is expected to be similar to that of other actinide dihalides, possibly adopting a structure related to the lead(II) chloride structure. Due to the instability of the +2 oxidation state of americium, AmBr2 is expected to be highly reducing. Research on americium(II) bromide is limited, with most studies focusing on more stable americium compounds. The compound is primarily of interest in academic research concerning the fundamental chemistry of the actinide elements.
