Dicarbon monoxide

Dicarbon monoxide (C2O) is an extremely reactive molecule that contains two carbon atoms and one oxygen atom. It is covalently bonded. It is an intermediate in the photolysis of carbon suboxide. It is closely related to CO, CO2 and C3O2, and other oxides of carbon.


 * C3O2 → CO  + C2O

It is stable enough to observe reactions with NO and NO2.

Dicarbon monoxide is often referred to as DCM.
