Zinc acetylacetonate is an acetylacetonate complex of zinc, with the chemical formula of Zn(C5H7O2)2. The compound is in fact a trimer, Zn3(acac)6, in which each Zn ion is coordinated by five oxygen atoms in a distorted trigonal bipyramidal structure.[5] Hydrated zinc acetylacetonate can be obtained by combining zinc sulfate, acetylacetone, and sodium hydroxide.[3]
