Derek Lowe tells the story of “carbyne”, a potential further allotrope of carbon, comprising linear chains of carbon atoms, C-C≡C-C≡C-C. Whether such a molecule can exist on its own has long been the the topic of speculation. Now a report has appeared of a “pseudocarbyne”, stabilised by gold atoms.

With AI and Machine learning needing data in abundance, interest in data discovery is intense. However, this type of discovery is somewhat different from more traditional data base searches, in that it is particularly suited for machine discovery as well as by humans.

In exploring one-electron carbon-carbon bonds, I had noted previously that both hexafluoroethane and ethane itself could each lose an electron to produce such species. A discussion developed in which a molecule isoelectronic with ethane, namely the methyl-λ1-borane radical (H3B-CH3) was proposed by Jacob.

In the previous post, I looked at the recently reported hexa-arylethane containing a carbon-carbon one-electron bond, its structure having been determined by x-ray diffraction (XRD). The measured C-C bond length was ~2.9aÅ and my conclusion was that the C…C region represented more of a weak “interaction” than of a bond as such. How about a much […]
