Abstract

Literature data on complex hydrides of the late transition metals (groups 7–10), such as the hydrogen storage material Mg~2~NiH~4~, are reviewed with respect to order-disorder phase transitions and structural relationships. They are analysed in terms of crystallographic group-subgroup trees and their use in understanding the different crystal structures from a symmetry point of view is demonstrated. New data are presented on the low temperature behaviour of magnesium iridium hydrides and strontium rhodium hydrides studied by powder X-ray diffraction.
