Abstract
- A novel low-temperature hydride, Mg3MnNi2D3−x with filled Ti2Ni-type structure has been synthesised and its crystal structure has been studied in detail by powder neutron diffraction. Refinement of the structures of β-Mg3MnNi2D1.83 and α-Mg3MnNi2D0.23 deuteride phases showed that D atoms partially fill 16d Mg6 octahedral and 32e Mg3Ni tetrahedral interstices in the cubic metal matrix (sp.gr. View the MathML sourceFd3¯m). The β-hydride was found to be rather unstable, during storage in air it transforms into α-hydride.
