Effect of oxalic acid solution on tin(II) oxide :

 

Tin(II) oxalate can also be obtained by using tin(II) chloride and oxalic acid.[3]

Properties

edit

Tin (II) oxalate forms colorless crystals.

Insoluble in water and acetone. Soluble in dilute HCl,[4] methanol, and petroleum ether.[5]

Forms crystal hydrates of the composition SnC2O4n H2O, where n = 1 and 2.

Decomposes on heating:

 

Applications

edit
  • Tin oxalate is used as a catalyst in the production of organic esters and plasticizers.[4]
  • It is used for dyeing and printing fabrics.
  • The compound is also used in stannous oral care compositions.
  • Few studies have reported on the use of tin(II) oxalate as an anode material for rechargeable lithium batteries.[6]
