Lutetium(III) bromide is a crystalline compound made of one lutetium atom and three bromine atoms.[2] It takes the form of a white powder at room temperature.[1] It is hygroscopic.[2] It is odorless.[5]

Properties

Reactions

Lutetium(III) bromide can be synthesized through the following reaction:[6]

2 Lu(s) + 3 Br2(g) → 2 LuBr3(s)

If burned, lutetium(III) bromide may produce hydrogen bromide and metal oxide fumes.[5]

Lutetium(III) bromide reacts to strong oxidizing agents.[5]

Solubility

An experiment by T. Mioduski showed that the solubility of LuBr3 in tetrahydrofuran at 21-23 °C was 0.30 g per 100 ml of solution.[7]
