Infobox references

Carbon tetroxide is a highly unstable oxide of carbon with formula CO
4. It was proposed as an intermediate in the O-atom exchange between carbon dioxide (CO
2) and oxygen (O
2) at high temperatures.^[1]

The equivalent carbon tetrasulfide is also known from inert gas matrix. It has D_2d symmetry with the same atomic arrangement.^[2]
