Infobox references

Samarium(III) 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]
