Dicarbon monoxide (C2O) is an extremely reactive molecule that contains two carbon atoms and one oxygen atom. Dicarbon monoxide, covalently bonded, is a product of the photolysis of carbon suboxide.[1][2] It is closely related to CO, CO2 and C3O2, and other oxocarbons.
It is stable enough to observe reactions with NO and NO2.[3]
