Tetracarbon dioxide is a chemical compound from the group of oxides . It is the fourth member of the series of linear carbon dioxides O (= C) _n = O, which includes carbon dioxide O = C = O, ethendione O = C = C = O, carbon suboxide O = C = C = C = O and so on .

Extraction and presentation

The compound was first obtained in 1990 by Günther Maier and others through the photolysis of diazoketones in an argon matrix and is the first carbon dioxide with an even number of carbon atoms .

properties

Tetracarbon dioxide likely has a triplet ground state.
