Cyclohexanehexathione (original) (raw)

Cyclohexanehexathione is a cyclic covalent compound consisting of a six-carbon ring with a sulfur bonded to each. It has been generated by neutralization of its monoanion (C6S−6) in a mass spectrometer. This compound is the thioketone analog of cyclohexanehexone; that oxygen variant is expected to be substantially less stable. Synthesis of C6S6 by photolysis or pyrolysis to extrude three equivalents of carbon monoxide from a precursor containing adjacent pairs of sulfurs as cyclic dithiocarbonate units gave what is more likely a different valence isomer, as various dithiete-containing structures are predicted to be more stable than the hexathione form.
