Paywalled, but here's the Science Daily story explaining the result.<p><a href="https://www.sciencedaily.com/releases/2024/09/240925122902.htm" rel="nofollow">https://www.sciencedaily.com/releases/2024/09/240925122902.h...</a><p>The chemical is described as a derivative of hexaphenyl ethane, where hindrance of the six phenyl groups would stretch ethane's C-C bond. The "extremely close together" in the Science Daily article would seem to be wrong, I'd think.<p>Correction: it's not hexaphenyl ethane; "derivative" was doing some heavy lifting there.
