Coordination of Aliphatic C-H Bonds Agostic Interactions

Intramolecular Coordination of Aliphatic C-H Bonds (Agostic Interactions) 

An titanium alkyl with severe distortion from an agostic interaction. 

These two interactions can be considered intermediates in a-elimination processes. Agostic interactions between unsaturated metals and ligand C-H bonds are also common, such as in the precursor to Kubas s dihydrogen complex,in [Ru(PPh3)3ClJ, and in a highly unsaturated palladium(II) and Rh(I) species.
