Tin(IV) acetate explained

Tin(IV) acetate is the acetate salt of tin(IV), with the chemical formula of Sn(CH₃COO)₄.

Preparation

Tin(IV) acetate can be refluxed by thallium acetate and tin(IV) iodide in acetic anhydride. After the reaction is completed, the solution is concentrated and cooled to precipitate crystals, which are washed with anhydrous ether and dried in vacuum:

4 CH₃COOTl + SnI₄ → Sn(CH₃COO)₄ + 4 TlI↓

Tetraphenyltin is refluxed at 120 °C in acetic acid-acetic anhydride mixture, and tin(IV) acetate can be quantitatively generated:^[1]

4 CH₃COOH + (C₆H₅)₄Sn → Sn(CH₃COO)₄ + 4C₆H₆

The reaction of tin(IV) nitrate with acetic acid and acetic anhydride can also produce tin(IV) acetate, but the reaction with trifluoroacetic anhydride can not get its analogue, but (NO₂)₂[Sn(CF₃COO)₆].^[2]

4 CH₃COOH + Sn(NO₃)₄ → Sn(CH₃COO)₄ + 4 HNO₃

Properties

Tin(IV) acetate decomposes in water to form tin hydroxide and acetic acid:

Sn(CH₃COO)₄ + 4 H₂O → Sn(OH)₄ + 4 CH₃COOH

It reacts with sulfur-containing species such as thiols to generate corresponding sulfur-containing tin compounds.^[3]
