Holmium acetylacetonate

Holmium acetylacetonate is a coordination compound with the formula Ho(C₅H₇O₂)₃. This anhydrous acetylacetonate complex is often discussed but unlikely to exist per se. The 8-coordinated dihydrate Ho(C₅H₇O₂)₃(H₂O)₂ is a more plausible formula based on the behavior of other lanthanide acetylacetonates. The dihydrate has been characterized by X-ray crystallography.^[1]
