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.^[4] Its anhydrous form is stable in a dry atmosphere but forms a hydrate in humid air.^[5]

Like related lanthanide acetylacetonates, the complex is usually isolated with additional ligands. The dihydrate, which has been characterized by X-ray crystallography, features 8-coordinate Ho(III).^[6] No crystallographic evidence has been reported for anhydrous derivatives.
