Abstract
Agostic interaction geometries, C-H … M (M = Li, Group 4 or 5 transition metal or other), have been investigated with data retrieved from the Cambridge Structural Database. Analysis of both neutron- and X-ray-derived structures shows that a strengthening of the H … M agostic bond is accompanied by a corresponding weakening of the C-H bond. A similarity in behaviour of Li to the heavier transition metals is observed in these agostic interactions. Di- and tri-bridged C-H … Li geometries involving alkyl groups occur in both intra- and inter-molecular cases.
