Published in Henry Rzepa's Blog

Six years ago, I posted on the nature of a then recently reported[cite]10.1002/anie.200803859[/cite] Cr-Cr quintuple bond. The topic resurfaced as part of the discussion on a more recent post on NSF 3 , and a sub-topic on the nature of the higher order bonding in C 2 . The comment made a connection between that discussion and the Cr-Cr bond alluded to above.
