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. It is a ferromagnetic semiconductor.

Production

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

Eu + H₂ → EuH₂

Uses

EuH₂ can be used as a source of Eu to create metal-organic frameworks that have the Eu ion.
