Tin(II) acetate
# Tin(II) acetate

Tin(II) acetate is the acetate salt of tin(II), with the chemical formula of $Sn(CH_3COO)_2.$ It was first discovered in 1822.

## Preparation

To obtain tin(II) acetate, tin(II) oxide is dissolved in glacial acetic acid and refluxed to obtain yellow $Sn(CH_3COO)_2·2CH_3COOH$ when cooled. The acetic acid can be removed by heating under reduced pressure, and the white $Sn(CH_3COO)_2$ crystals can be obtained by sublimation.

## Properties

$Sn(CH_3COO)_2·2CH_3COOH$ undergoes disproportionation and decomposition when heated under normal pressure, and products such as tin(IV) oxide and hydrogen are generated. The decomposition of anhydrous $Sn(CH_3COO)_2$ is to the blue-black tin(II) oxide.

Anhydrous $Sn(CH_3COO)_2$ decomposes in water, but complexes such as $KSn(CH_3COO_2)_3$ and $Ba[Sn(CH_3COO)_3]_2$ can be formed in alkali metal or alkaline earth metal acetates.
