Samarium acetylacetonate is a coordination compound with the chemical formula Sm(C₅H₇O₂)₃, or Sm(acac)₃ for short. It can react with N-bromosuccinimide in chloroform to give light yellow Sm(Br-acac)₃ (where Br-acac is 3-bromo-2,4-pentanedione ligand).[1] Its hydrate can be recrystallized in DMSO to obtain Sm(acac)₃·2DMSO·H₂O.[2] It reacts with dicobalt octacarbonyl and can be used to prepare SmCo₅.[3]
