Cerium(III) acetylacetonate is a compound with formula Ce(C5H7O2)3(H2O)x. It is typically isolated as the trihydrate. Partial dehydration gives the dihydrate, a red-brown solid.[2]


Cerium acetylacetonate is a precursor to mesoporous nanocrystalline ceria using the sol-gel process.[3] It can also be used along with gadolinium acetylacetonate to synthesize gadolinia-doped ceria (GDC) gel powders.[4]
