Zinc acetylacetonate is an acetylacetonate complex of zinc, with the chemical formula of Zn(C
5H
7O
2)
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]
Preparation
Zinc acetylacetonate can be obtained by reacting zinc sulfate, acetylacetone and sodium hydroxide.[3]
Properties
Zinc acetylacetonate is a crystalline substance that is slightly soluble in water.[1] Through sublimation, monomer crystals can be obtained, which are monoclinic and have the space group C2/c (No. 15).[6] Trimeric crystals can also be obtained by sublimation, which is also monoclinic, with space group C2 (No. 5).[2] The structures of its monohydrate[7] and dihydrate[8] are also known.
Reactions
Zinc acetylacetonate hydrate has been used to prepare magnetic (Zn,Fe)Fe2O4 films,[9] zinc oxide,[10] and is also a catalyst for organic synthesis.[3]
