Neodymium(III) hydride is an inorganic compound composed of neodymium and hydrogen with a chemical formula NdH3. In this compound, the neodymium atom is in the +3 oxidation state and the hydrogen atoms are −1. It is highly reactive.
Preparation
Neodymium(III) hydride can be produced by directly reacting neodymium and hydrogen gas:4
2Nd + 3H2 → 2NdH3It can also be made by hydrogenerating neodymium(II) hydride.5
Properties
Neodymium hydride is a blue crystal of the hexagonal system, with unit cell parameters a=0.385 nm, c=0.688 nm.6
It reacts with water to form neodymium hydroxide and hydrogen gas:7
NdH3 + 3 H2O → Nd(OH)3 + 3 H2See also
