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 ...
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 ).
The general structure of an oxocarbenium ion. An oxocarbenium ion (or oxacarbenium ion) is a chemical species characterized by a central sp 2-hybridized carbon, an oxygen substituent, and an overall positive charge that is delocalized between the central carbon and oxygen atoms. [1]
It is an oxocarbon anion that consists solely of carbon and oxygen. It is the anion of peroxycarbonic acid [1] [2] also called hydroperoxyformic acid, [3] HO−O−CO−OH. The peroxycarbonate anion is formed, together with peroxydicarbonate C 2 O 2− 6, at the negative electrode during electrolysis of molten lithium carbonate. [4]
The carbonate ion is the simplest oxocarbon anion. It consists of one carbon atom surrounded by three oxygen atoms, in a trigonal planar arrangement, with D 3h molecular symmetry. It has a molecular mass of 60.01 g/mol and carries a total formal charge of −2.

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–. The anion is formed, together with peroxocarbonate CO 2− 4, at the negative electrode during electrolysis of molten lithium carbonate. [1]
