Dewar−chatt−duncanson model
Did you know?
Webmost commonly used description of M−CO bonding when M = transition metal (TM) uses the Dewar−Chatt−Duncanson model (DCD), namely, σ-donation from the CO group to an empty orbital of the TM and π-back-donation from the TM to a π* orbital of the CO group.2 The back-bonding into the unoccupied π* orbital of the CO group is used as well to WebThis concept is enshrined in the well-accepted Dewar-Chatt-Duncanson model of transition-metal bonding. We present herein experimental and computational evidence for the first true violation of the Dewar-Chatt-Duncanson bonding model, found in a π-diborene complex in which an electron-rich group 10 metal donates electrons into an …
