Tin(IV) acetate, also known as stannic acetate or tetra-acetoxytin [Sn(OAc)₄], is a moisture-sensitive white crystalline solid with a melting point of approximately 232–233 °C and decomposition occurring above 260 °C. It features a tetra-coordinated Sn⁴⁺ center bonded to acetate ligands, which are readily displaced in polar protic or aprotic solvents. This confers excellent solubility in alcohols, acetic acid, glycols, and coordinating ethers, along with moderate volatility—making it suitable for vapor deposition processes. As a Lewis acid, Tin(IV) acetate is widely utilized in organic transformations, polymerization catalysis, and as a sol-gel precursor for the synthesis of nanomaterials and eco-friendly thin films.

Tin(IV) acetate can be used:

• As a reducing agent to synthesize silver nanoparticles for conductive inks for printed electronics.
• As a precursor to prepare tin oxide nanopowder for gas sensors.
