Ruthenium is usefull transition metal to study the coordination of H2 without breaking the H-H bound (sigma H2). With this element, it has been possible to charaterized by neutron diffraction techniques for the first time the coordination of two H2 molecules. The mechanism exchange between the different types of hydrogen present in that molecules have been determined.

This complex is able to reversibly release up to 1.7% w/w of hydrogen. This complex is a model research to lighter transtition metal complexes ables to reversibly deliver a high quantity of hydrogen from different type of hydrogen sources (sigma H2, Hydrides, Hydrogen in auxillary ligands).

This project is partially supported by a french grant ANR "3H2" 2015-2019
