Tin(II) oxalate is an inorganic compound, a salt of tin and oxalic acid with the chemical formula SnC2O4.[2] The compound looks like colorless crystals, does not dissolve in water, and forms crystalline hydrates.

Synthesis

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

[math]\displaystyle{ \mathsf{ SnO + H_2C_2O_4 \ \xrightarrow{}\ SnC_2O_4\downarrow + H_2O } }[/math]

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

Properties

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:

[math]\displaystyle{ \mathsf{ SnC_2O_4 \ \xrightarrow{380^oC}\ SnO_2 + 2CO } }[/math]

Applications

  • 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]
