Rare earth-transition metal-cadmium intermetallics – crystal chemistry and physical properties

MgCuAl2-type Intermetallics REPdCd2(RE = Ce, Pr, Nd, Sm)

“…Especially LaNiMg 2 has intensively been studied with respect to its hydrogenation behavior [10, 14 -20], when searching for new hydrogen storage materials. Given the close structural relationship between RE x T y Mg z [21] and RE x T y Cd z [22] intermetallic compounds, one can also consider RETCd 2 compounds in this context. So far only LaNiCd 2 [12], PrNi 0.951 Cd 2 and LaPdCd 2 [23] have been reported.…”

Ca2Pd2Cd with W2B2Co-type Structure

“…In total each metal cation has six palladium and Fig. 2 In summary, the substitution of the rare earth atoms in RE x T y Cd z phases [32] by alkaline earth metals offers interesting new structural possibilities. The change in size and VEC leads to different structural motifs.…”

Dimorphic EuCu5Cd

“…The rare earth (RE) transition metal (T ) cadmium compounds display a large diversity of structural features [1]. However, in contrast to the RE x T y Mg z [2] and especially RE x T y Zn z [3] compounds, only few examples with larger cadmium content are known.…”
