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]
