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]
Through sublimation, both monomeric and trimeric forms can be obtained. The monomer is monoclinic and have the space group C2/c (No. 15). [6] Anhydrous zinc acetylacetonate also exists in the solid state as a trimer. [2]
The anhydrous zinc acetylacetonate is Lewis acidic, giving 5- and 6-coordinate adducts of the formula Zn(acac)2L and Zn(acac)2L2, respectively. The structures of its monohydrate [7] and dihydrate [8] are also known.
Thermal decomposition of zinc acetylacetonate gives zinc oxide, [9] and is also a catalyst for organic synthesis. [3]
