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.[4] It is a ferromagnetic semiconductor.[5]

Production

Europium hydride can be produced by directly reacting europium and hydrogen gas:[4]

Eu + H₂ → EuH₂

Uses

EuH₂ can be used as a source of Eu²⁺ to create metal-organic frameworks that have the Eu²⁺ ion.[2]
