Hydrogen-bridged silicon-transition metal

Complexes with Hydrogen-Bridged Silicon-Transition Metal Bonds... 

Structure//was one of the first known examples of hydrogen bridges between a transition metal and a main-group element other than boron. There are many interesting features in syntheses, bonding properties, and reactions of silicon-transition-metal compounds which can only be outlined in this article, which covers the literature up to 1973. But any survey achieves its aim if it stimulates further interest and research in its specific area. 

Bulky alkyl groups CH2R (R = Ph, CMca, SiMe, or CMo Pli), which have no hydrogen atoms attached to the carbon or silicon atom in the p position, have been widely used to probe the alkyl chemistry of transition metals Uieir bulk protects the metal from nucleophilic attack, while the absence of 3 hydrogen reduces the risk of decomposition by metal hydride formation and alkene elimination. The use of such ligands attached to manganese has provided examples of hypercarbon atoms bridging pairs of metal atoms that are worthy of brief mention here.
