Characteristic

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.

Formula: CoC2O4•2H2O

Formula weight: 182.98g/mol (146.95anhy)

Appearance:Light pink powder

Melting Point: 229-231°C

Density 3.021g/ml

Sensitivity: Ambient temperatures.

Solubility: Soluble in aqueous ammonia. Insoluble in water. Slightly soluble in acids.

Application

It is used in the preparation of cobalt catalysts, and cobalt metal powder for powder-metallurgical applications. It is made in process of recycling lithium-ion batteries, where the cobalt is obtained from cathode material (LiCoO2) by leaching with sulfuric acid and then precipitated with ammonium oxalate.
