Chemical Properties Zinc acetate occurs as white crystalline, lustrous plates with a faint acetic odor and an astringent taste.

Physical properties The acetate group is capable of binding to metal ions in a variety of ways through its two oxygen atoms and several connectivities are observed for the various hydrates of zinc acetate. Anhydrous zinc acetate adopts a polymeric structure consisting of zinc coordinated to four oxygen atoms in a tetrahedral environment, each tetrahedron being connected to neighbors by the acetate groups . The acetate ligands are not bidentate. In contrast, most metal diacetates feature metals in octahedral coordination with bidentate acetate groups. In zinc acetate dihydrate the zinc is octahedral, wherein both acetate groups are bidentate.

Heating Zn(CH3CO2)2 in a vacuum results in loss of acetic anhydride, leaving a residue of ""basic zinc acetate,"" with the formula Zn4O(CH3CO2)6. This cluster compound has the tetrahedral structure shown below. This species closely resembles the corresponding beryllium compound, although it is slightly expanded with Zn-O distances ～1.97 vs ～1.63 Å for Be4O(OAc)6.

Uses Zinc acetate is produced from acetic acid and zinc oxide. It is used for preserving wood, manufacturing glazers for painting on porcelain; as a reagent in testing for albumin, tannin, phosphate; as cross-linking agents for polymers; in tobacco smoke filters; and as a topical fungicide. Zinc acetate is an indirect food additive for use only as a component of adhesives.

Uses Medicine (astringent), preserving wood, textile dyeing (mordant and resist), zinc chromate, laboratory reagent, cross-linking agent for polymers, ingredient of dietary supplements (up to 1 mg daily), feed additive, ceramic glazes.
