Chemical compound

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.

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.

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.
