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]
Lutetium(III) bromide can be synthesized through the following reaction:[6]
If burned, lutetium(III) bromide may produce hydrogen bromide and metal oxide fumes.[5]
Lutetium(III) bromide reacts to strong oxidizing agents.[5]
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]
