Cobalt(II) oxalate is the inorganic compound with the formula of CoC2O4. Like other simple inorganic oxalates, it is a coordination polymer. The oxalate ligands bridge of Co(OH2)2 centres. Each cobalt adopts octahedral coordination geometry.
It is used in the preparation of cobalt catalysts, and cobal metal powder for powder-metallurgical applications. It is made in process of recycling lithium-ion bateries, where the cobalt is obtained from cathode material (LiCoO2) by leaching with sulfuric acid and then precipitated with ammonium oxalate.
