Oxalate (IUPAC: ethanedioate) is an anion with the formula C2O4 . This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na2C2O4), and several esters such as dimethyl oxalate (C2O4(CH3)2). It is a conjugate base of oxalic acid. At neutral pH in aqueous solution, oxalic acid converts completely to oxalate. WebSolid iron(II) ethanedioate dihydrate (FeC2O4.2H2O) has a polymeric structure. Two repeating units in the polymer chain are shown. Each iron ion is also bonded to two water molecules. These are not shown in the diagram.
