The structure of the oxalate anion

An oxalate (also ethanedioate) is the deprotonated, charged form of oxalic acid. As a salt, the oxalate anion has the chemical formula C₂O₄²⁻ or (COO)₂²⁻.

Consumption of oxalates (for example, the grazing of animals on oxalate-containing plants such as greasewood), or human consumption of Sorrel may result in kidney disease or even death due to oxalate poisoning. The presence of Oxalobacter formigenes in the gut flora can prevent this.

The charge on oxalate allows it to act as a chelator of various positively charged metal ions.

For more detail, see the main entry oxalic acid.

Examples

• sodium oxalate - Na₂C₂O₄
• calcium oxalate - CaC₂O₄, a major component of kidney stones
• dimethyl oxalate - (CH₃)₂C₂O₄
• phenyl oxalate ester - (C₆H₅)₂C₂O₄
• potassium ferrioxalate - [K₃[Fe(C₂O₄)₃], an iron complex with oxalate ligands
• ammonium oxalate - (NH₄)₂C₂O₄
