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.[4]
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).[5] Trimeric crystals can also be obtained by sublimation, which is also monoclinic, with space group C2 (No. 5).[2] The structures of its monohydrate[6] and dihydrate[7] are also known.
Applications
Zinc acetylacetonate hydrate can be used to make magnetic (Zn,Fe)Fe2O4 films,[8] zinc oxide,[9] and is also a catalyst for organic synthesis.[3]
