Effect of carbon-containing compounds on the hydriding behavior of nanocrystalline Mg2Ni

By means of X-ray structural analysis, the isothermal section of the Fe–Zn–Sb phase diagram at 570 K has been built. Two ternary compounds have been found. The FeZnSb2 compound crystallized in the NiAs structure type, and the FeZnSb compound in the MgAgAs structure type. The crystal structure of FeSb2 (FeS2 structure type) has been refined by single crystal diffraction.
