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.

[2][3] Upon heating under vacuum, the dihydrate converts to the oxo-cluster Gd4O(C5H7O2)10.

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