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]
