Europium hydride is the most common hydride of europium with a chemical formula EuH2. In this compound, europium atom is in the +2 oxidation state and the hydrogen atoms are -1.[3] It is a ferromagnetic semiconductor.[4]
Production
Europium hydride can be produced by directly reacting europium and hydrogen gas:[3]
- Eu + H2 → EuH2
Uses
EuH2 can be used as a source of Eu2+ to create metal-organic frameworks that have the Eu2+ ion.[1]
