Gadolinium acetylacetonate is a coordination compound with the formula Gd(C₅H₇O₂)₃. This anhydrous acetylacetonate complex is widely discussed but unlikely to exist per se. The 8-coordinated dihydrate Gd(C₅H₇O₂)₃(H₂O)₂ is a more plausible formula based on the behavior of other lathanide complexes. It has also been characterized twice by X-ray crystallography.^[2]^[3]

Upon heating under vacuum, the dihydrate converts to the oxo-cluster Gd₄O(C₅H₇O₂)₁₀. This behavior is also observed for europium acetylacetonate, yttrium acetylacetonate, lanthanum acetylacetonate, and erbium acetylacetonate.^[4]

Uses

Gadolinium acetylacetonate, along with cerium acetylacetonate, can be used as precursors to synthesize gadolinia-doped ceria (GDC) gel powders using the sol-gel method. ^[5]
