Abstract

original image

Big can be small: The largest ligand-stabilized magnesium hydride cluster, containing 8 Mg2+ and 10 H ions, is a model for the smallest sub-nanometer-sized hydrogen storage material. This molecular cluster displays magnetic hydride–hydride coupling (see picture) and complete hydrogen desorption at the record-low temperature of 200 °C.
