Abstract

The interaction of hydrogen with metal surfaces is one of the most important and fundamental processes in the chemical industry. Hydrogen is also strongly tipped to play a central role in new challenges that are emerging in terms of climate change and energy supply, and the reversible binding of H~2~ to suitable materials will play a keystone role in the realisation of the hydrogen economy. The reversible interaction of hydrogen with multimetallic centres is also an important theme in biological processes; the role of hydrogenases in the metabolism of H~2~ is an example. Thus the reversible interaction of H~2~ with multimetallic metal complexes is an area that spans considerable breadth. This review is concerned with the reversible interaction of H~2~ with soluble multimetallic complexes, defined broadly as clusters, in which there are no other ligands lost or gained in the process. The review is organised under the subheadings: equilibrium reversible (H~2~ is lost upon removal of the H~2~ atmosphere), thermally reversible or reversible when placed under vacuum, photochemically reversible and electrochemically reversible interactions; a brief outline of reversible H~2~ binding in systems of biological interest; giant metal clusters that display reversible H~2~ binding.
