Samarium(III) bromide is a crystalline compound of one samarium and three bromine atoms with the chemical formula of SmBr₃. Samarium(III) bromide is a dark brown powder at room temperature.^[4] The compound has a crystal structure isotypic to that of plutonium(III) bromide.^[5]^[6]

Preparation

SmBr₃·6H₂O can be crystallized by dissolving samarium oxide in 40% hydrobromic acid. The hydrate and ammonium bromide are heated in a vacuum to obtain the anhydrous form of samarium(III) bromide.^[2]

Other compounds

Samarium(III) bromide forms some compounds with hydrazine, such as SmBr₃·3N₂H₄·H₂O which is a pale yellow needle-shaped crystal that is soluble in water and ethanol but insoluble in benzene, with d_20 °C = 3.147 g/cm³.^[7]
