Tin(IV) acetate, also known as stannic acetate, is the tin(IV) salt of acetic acid, 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:
- 4 CH3COOH (C6H5)4Sn → Sn(CH3COO)4 4 C6H6
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 [NO 2]2[Sn(CF3COO)6]2− (nitronium hexaacetatotin(IV)).
- 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.
