Neodymium(III) hydride is an inorganic compound composed of neodymium and hydrogen with a chemical formula NdH₃.^[2]^[3] In this compound, the neodymium atom is in the +3 oxidation state and the hydrogen atoms are -1. It is highly reactive.^[4]

Preparation

Neodymium(III) hydride can be produced by directly reacting neodymium and hydrogen gas:^[5]

2Nd + 3H₂ → 2NdH₃

It can also be made by hydrogenerating 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
