Zirconyl acetate is the coordination complex with the formula Zr6O4(OH)4(O2CCH3)12. It is a chemical compound that consists of zirconium, oxygen, and acetate ions. It is a white solid prepared by treating zirconyl chloride with acetic acid. The compound has attracted attention as a precursor to metal-organic frameworks. The structure of the 8.5 hydrate has been determined by EXAFS. The core can be described as a Zr6 octahedron is face-capped with oxide and hydroxide ligands. It is typically used in various industrial applications, including as a catalyst in organic synthesis and as a precursor for other zirconium compounds.
Physical Properties
