摘要：

The present study gives an overview of the fundamental material properties of perovskite-type hydrides. Formation ability of the perovskite-type hydrides has been reasonably explained on the basis of the geometric restrictions on the composed ions using the Goldschmidt tolerance factor. Characteristic crystal structures and charge density maps of the perovskite-type hydrides without/with transition metals, such as NaMgH3/CaNiH3, were also examined in detail to clarify the relationship between the structures (atomic and electronic) and the hydriding properties.
