This theoretical molecule is a ring of six carbon atoms, connected by alternating double bonds.

There have been a few attempts to synthesize cyclo[6]carbon, e.g. by pyrolysis of mellitic anhydride,[2] but without success until 2023, when it was successfully synthesised by atom manipulation of hexachlorobenzene, although more thorough research has yet to be reported in peer reviewed scientific work.

Cyclo[6]carbon would present then low probability of formation due to its high energy state from a thermodynamical perspective, which is reflected on the lack of evidence of its successful synthesis.

Calculations suggest that the alternative cyclic cumulene structure, called cyclohexahexaene, is the potential energy minimum of the cyclo[6]carbon framework.
