Dihydrogen coordination chemistry

Another milestone in coordination chemistry dates from 1980, when the first complex containing dihydrogen was reported by G. J. Kubas. ft was found that hydrogen reacts with [W(CO)2(Pchx3)2]... 

Just as bridging hydrides play a central role in the chemistry of Group 13 hydrides, three centre-two electron (3c-2e) bonding is a recurrent fea- Figure 2.17 Polyhydride vs ture of binuclear (and polynuclear) hydrides of the transition metals dihydrogen coordination...

Particularly since the initial discovery of dihydrogen complexes by Kubas [48], the coordination chemistry of H2 has revealed rich complexity [49]. There is little information on the precise pathway by which hydrogen adds to coordinative-... 

In general, coordination chemistry of water-soluble phosphine complexes and their reaction with dihydrogen show many similarities to reactions of their water-insoluble analogs. Active hydrogenation catalysts or catalyst precursors, such as...

Like dioxygen [102], dihydrogen behaves as both a ligand in coordination chemistry and a transferable reagent in catalysis. In cataljdic processes, dihydrogen can play three different roles, the third of which represents a unique chemical characteristic ... 

The isolation and full characterization of dihydrogen complexes by Gregory Kubas in 1984 represents a pivotal point in coordination chemistry.Other discoveries soon followed and the three examples selected for Figure 2 represent various impacts of these mononuclear complexes on fundamental understanding.

Two significant surveys are published in the sane edition of Coordination Chemistry Reviews. Oxygen donor-ligand derivatives of tri-osmium dodecacarbonyl are covered by Frauenhoff and the reactions of transition metal dihydrogen complexes (of which many are carbonyl-containing) are outlined by Jessop and Morris. The crucial role of matrix Isolation studies is well covered in this article. A shorter review of interest here has been published on the role of the phosphorus d-orbitals in M-P bonding. ... 

A further indication of the rapid advances that have occurred in the chemistry of the elements during the past 15 years can be gauged from the several completely new sections which have been added to review work in what were previously both nonexistent and unsuspected areas. These include (a) coordination compounds of dihapto-dihydrogen, (b) the fullerenes and their many derivatives, (c) the metcars, and (d) high-temperature oxide superconductors.
