Neodymium(III) bromide is an inorganic salt of bromine and neodymium the formula NdBr3. The anhydrous compound is an off-white to pale green solid at room temperature, with an orthorhombic PuBr3-type crystal structure.[6][7] The material is hydroscopic[8][9] and forms a hexahydrate in water (NdBr3· 6H2O), similar to the related neodymium(III) chloride.[10]
Preparation
The direct reaction of neodymium with bromine can create neodymium(III) bromide:
- 2Nd + 3Br2 → 2NdBr3
In the presence of carbon, neodymium(III) oxide reacts with carbon tetrabromide to produce neodymium(III) bromide.[11]
Related compounds
Neodymium(III) bromide forms compounds with hydrazine, such as NdBr3·N2H4·2H2O, which is a pink crystal that is soluble in water but insoluble in benzene, with d20°C = 3.2376 g/cm3.[12]
