Preparation
Neodymium(III) hydride can be produced by directly reacting neodymium and hydrogen gas:[5]
- 2Nd + 3H2 → 2NdH3
It can also be made by hydrogenating neodymium(II) hydride.[6]
Properties
Neodymium hydride is a blue crystal of the hexagonal system, with unit cell parameters a=0.385 nm, c=0.688 nm.[7]
It reacts with water to form neodymium hydroxide and hydrogen gas:[8]
- NdH3 + 3 H2O → Nd(OH)3 + 3 H2
