In chemistry, an oxocarbon or oxide of carbon is a chemical compound consisting only of carbon and oxygen. [ 1 ] [ 2 ] The simplest and most common oxocarbons are carbon monoxide (CO) and carbon dioxide ( CO 2 ).
In chemistry, peroxycarbonate (sometimes peroxocarbonate, IUPAC name: oxocarbonate or oxidocarbonate) or percarbonate is a divalent anion with formula CO 2− 4. It is an oxocarbon anion that consists solely of carbon and oxygen. It would be the anion of a hypothetical peroxycarbonic acid HO−CO−O−OH (sometimes peroxocarbonic acid).
In chemistry, an oxocarbon anion is a negative ion consisting solely of carbon and oxygen atoms, and therefore having the general formula C x O n− y for some integers x, y, and n. The most common oxocarbon anions are carbonate, CO 2− 3, and oxalate, C 2 O 2− 4. There are however a large number of stable anions in this class, including ...

There are several oxocarbon anions, negative ions that consist solely of oxygen and carbon. The most common are the carbonate (CO 3 2−) and oxalate (C 2 O 4 2−). The corresponding acids are the highly unstable carbonic acid (H 2 CO 3) and the quite stable oxalic acid (H 2 C 2 O 4), respectively.
A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids , the conceptual anhydrides of carbonic acid , or polymers of carbon dioxide .
In chemistry, methanetetracarboxylate is a tetravalent anion with formula C 5 O 4− 8 or C(−CO − 2) 4. It has four carboxylate groups attached to a central carbon atom; so it has the same carbon backbone as neopentane. It is an oxocarbon anion, that is, consists only of carbon and oxygen.
In chemistry, peroxydicarbonate (sometimes peroxodicarbonate) is a divalent anion with the chemical formula C 2 O 2− 6. It is one of the oxocarbon anions, which consist solely of carbon and oxygen. Its molecular structure can be viewed as two carbonate anions joined so as to form a peroxide bridge –O–O–.
