Holmium acetylacetonate is a coordination complex, with the chemical formula of Ho(C5H7O2)3 or Ho(acac)3. It can be obtained via the reaction between metallic holmium[3] or holmium(III) hydride[1] with acetylacetone, or via the reaction between Holmium(III) chloride and ammonium acetylacetonate.[2] Its anhydrous form is stable in a dry atmosphere but forms a hydrate in humid air.[4]
