Dear Wenjie Ma,

Silver acetate can be synthesized by the reaction of acetic acid and silver carbonate at 45–60 °C. After allowing cooling to room temperature, the solid product precipitates.

2 CH3CO2H + Ag2CO3 → 2 AgO2CCH3 + H2O + CO2

It can also be precipitated from concentrated aqueous solutions of silver nitrate by treatment with a solution of sodium acetate.

The structure of silver acetate consists of 8-membered Ag2O4C2 rings formed by a pair of acetate ligands bridging a pair of silver centers.

Hoping this will be helpful,

Thanks a lot.

For better solubility in organic solvents you could also take a long chain carboxylic acid  and react it with silver carbonate.
