C 2 (dicarbon) is certainly interesting from a theoretical point of view. Whether or not it can be described as having a quadruple bond has induced much passionate discussion[cite]10.1038/nchem.1263[/cite],[cite]10.1002/anie.201208206[/cite],[cite]10.1002/anie.201301485[/cite],[cite]10.1002/anie.201302350[/cite]. Its occurrence in space and in flames is also well-known.

Critical Comments on “One Molecule, Two Atoms, Three Views, Four Bonds?”

The arguments that are given in the original trialogue in favor of a quadruply bonded C2, in which the bond is claimed to be stronger than that in HCCH, are judged invalid by the authors of this Correspondence. They also disagree with some statements about the stability of molecules and the virtue of chemical research beyond synthetic chemistry.
