Holmium acetylacetonate is a coordination complex with the formula Ho(C5H7O2)3 or Ho(acac)3. It is also known as holmium(III) acetylacetonate or Ho(acac)3. It is a chemical compound containing the rare earth element holmium (Ho). It can be produced by reacting metallic holmium or holmium(III) hydride with acetylacetone, or by reacting holmium(III) chloride with ammonium acetylacetonate. It is a coordination complex produced from acetylacetone (acacH) and holmium(III) ions.
In dry air, its anhydrous form is stable, but in humid air, it produces a hydrate. The compound, like related lanthanide acetylacetonates, is frequently isolated using additional ligands. X-ray crystallography was used to describe the dihydrate, which has 8-coordinate Ho(III). For anhydrous derivatives, no crystallographic evidence has been recorded.
