It was proposed as an intermediate in the O-atom exchange between carbon dioxide ({{chem|CO|2}}) and oxygen ({{chem|O|2}}) at high temperatures.[1] The equivalent carbon tetrasulfide is also known from inert gas matrix. It has D2d symmetry with the same atomic arrangement.[2] References1. ^{{ cite journal |author1=Yeung, L. Y. |author2=Okumura, M. |author3=Paci, J. T. |author4=Schatz, G.
