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]
