Neodymium(III) acetylacetonate is a coordination compound with the chemical formula Nd(O₂C₅H₇)₃. Although many sources discuss this anhydrous acetylacetonate complex, it is the dihydrate Nd(O₂C₅H₇)₃(H₂O)₂ that has been characterized by X-ray crystallography.^[2] It commonly occurs as a white powder.^[1]^[3] Upon heating under vacuum, other dihydrated lanthanide trisacetylacetonates convert to oxo-clusters M₄O(C₅H₇O₂)₁₀. This result suggests that Nd(O₂C₅H₇)₃ may not exist.^[4]

Preparation

Neodymium(III) acetylacetonate can be obtained by treating a neodymium alkoxide with acetylacetone,^[5] or by electrolysis of neodymium in acetylacetone.^[6]
