Scandium acetylacetonate is the coordination complex with the formula Sc(C₅H₇O₂)₃ where [C₅H₇O₂]⁻ refers to acetylacetonate. It is a volatile white solid that is soluble in benzene. The complex features Sc(III) with octahedral molecular geometry. ^[1] It was first prepared by treating scandium nitrate with acetylacetone in the presence of ammonia. ^[2]
