摘要：

The novel crystalline Mg-Pd alloy, Mg2PdC(x), was initially isolated through dehydrogenation of an amorphous hydride, Mg2PdC(x)H2 prepared using solution techniques. Further work showed that Mg2PdC(x) could also be obtained by heating Mg and Pd metals in thc presence of graphite. The carbide crystallizes with a cubic unit cell a = 12.0480(4) angstrom in space group Fd3BARm (227). The X-ray powder pattern could be refined on the basis of a Ti2Ni structural model with a final R(F) value of 0.047 for the metal atom substructure, Mg2Pd. Although the carbon atom position could not be refined, samples prepared by high temperature techniques indicated that the carbon content, x, can be as low as x = 0.1.
