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]


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

Eu + H2 → EuH2


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