Neutron Powder Diffraction, x-ray absorption and Mössbauer spectroscopy on Mg2FeH6

Mg2FeH6 was prepared by high-pressure reactions from simple hydrides. A Neutron Powder Diffraction (NPD) unveils details on crystal structure and H contents. No magnetic structure was observed at 2 K. A XANES study shows a zero oxidation state of Fe atoms in agreement with Mössbauer data.184
