Kubas interaction
http://diposit.ub.edu/dspace/bitstream/2445/165806/1/678184.pdf WebThe Kubas interaction is dominated by σ-donation from the H 2 to the metal for Cr(II), but is more balanced between σ-donation and π-back-donation for the Ti(II) and V(II) analogues. This difference in behaviour is traced to a lowering in energy of the metal 3d …
