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 hygroscopic[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]

Structure

Neodymium(III) bromide adopts the plutonium(III) bromide crystal structure.[12] The neodymium ions are 8-coordinate and adopt a bicapped trigonal prismatic geometry.[13] The neodymium–bromine bond lengths are 3.07 Å and 3.09 Å.[14]
