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]

Reactions

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]
