Europium(II) hydroxide is aninorganic compound, with the chemical formula of Eu(OH)2. It can exist as the dihydrate Eu(OH)2·H2O.
The monohydrate of europium(II) hydroxide can be obtained by the reaction of metaleuropium and 10 mol/Lsodium hydroxide solution.[1] There are some sources that useeuropium(III) chloride as a raw material, and prepare it by reacting theJones reductor withsodium hydroxide solution.[2]
Europium(II) hydroxide belongs to theorthorhombic crystal system, a=6.701 ± 0.002, b=6.197 ± 0.002, c=3.652 ± 0.001 A.[1] It thermally decomposes to formeuropium(II) oxide (EuO); it is readily oxidized toeuropium(III) hydroxide in air.[3]
