The single-electron bond (dashed line) comes about because the molecule’s central carbon–carbon bond is stretched, which makes it susceptible to losing one electron.

Typical carbon-carbon bonds in alkanes measure 1.54 Å. Since 2011, one of Schreiner’s diamondoid compounds held the record for containing the longest single carbon-carbon bond (Nature 2011, DOI ...

The single-electron bond was formed by subjecting a derivative of hexaphenylethane, which contains an extremely stretched out paired-electron covalent bond between two carbon atoms, ...
