Abstract
The low temperature phase of Mg2NiH4 was mechanically ground in argon atmosphere. The ordered monoclinic structure was destroyed to form the disordered cubic structure, previously only found above 510 K. With a Guinier-Hagg X-ray camera the cell parameter was determined to be a=6.492(3) Angstrom. By performing a Rietveld refinement on neutron diffraction data it was confirmed that the disordered structure is similar to the high temperature form of Mg2NiH4 (space group Fm3m).
