Cadmium oxalate is an inorganic compound with the chemical formula CdC2O4. It can be produced by reacting potassium oxalate and cadmium nitrate. [2] Its thermal decomposition in air produces cadmium oxide, [3] while metallic cadmium will be formed instead under vacuum. [4] It reacts with chalcogens in ethylenediamine to form the corresponding cadmium chalcogenide: [5]

CdC2O4 + E → CdE + 2 CO2↑ (E = S, Se, Te)
