Tin(II) acetate is the acetate salt of tin(II), with the chemical formula of Sn(CH₃COO)₂. It was first discovered in 1822.^[1]

Preparation

To obtain tin(II) acetate, tin(II) oxide is dissolved in glacial acetic acid and refluxed to obtain yellow Sn(CH₃COO)₂·2CH₃COOH when cooled. The acetic acid can be removed by heating under reduced pressure, and the white Sn(CH₃COO)₂ crystals can be obtained by sublimation.^[1]

Properties

Sn(CH₃COO)₂·2CH₃COOH 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(CH₃COO)₂ is to the blue-black tin(II) oxide.^[2]

Anhydrous Sn(CH₃COO)₂ decomposes in water,^[2] but complexes such as KSn(CH₃COO₂)₃ and Ba₂ can be formed in alkali metal or alkaline earth metal acetates.^[3]
