Erbium acetylacetonate

Erbium acetylacetonate is a coordination compound, with the chemical formula of Er(C5H7O2)3, or Er(acac)3 for short. It can be prepared by the reaction of metal erbium[2] or erbium trihydride[1] and acetylacetone. Erbium chloride could also react with ammonium acetylacetonate to obtain erbium acetylacetonate, which can be recrystallized in toluene.[3] Its anhydrous form is stable in dry atmosphere and forms a hydrate in humid air.[4] The anhydrous form cannot be obtained by heating the hydrate in humid atmosphere.[5] It begins to decompose at 190 °C, and erbium oxide can be obtained by continuous heating at 505 °C.[3]
