Lanthanide antimonides

Fig. 29. Chemical shift of the 4f level in the lanthanide antimonides relative to the pure metals (Martensson et al. 1982c).

Figure 3. The lattice parameter for the family of rock-salt structure actinide-antimonide compounds is shown where the line is for the corresponding lanthanide compounds. The metallic radii for the light actinide elements are plotted. The smooth line simply connects Ac to the heavy actinides. In both cases the smooth line represents the ideal tri-valent behavior.

No, the editor didn t know what this name meant either.) It means salts of the triva-lent anions of Group V, restricted in [1] to arsenides, antimonides and bismuthides and prepared by reaction of sodium pnictides with anhydrous halides of transition and lanthanide metals. This violently exothermic reaction may initiate as low as 25°C. Avoidance of hydrated halides is cautioned since these are likely to react uncontrollably on mixing. Another paper includes a similar reaction of phosphides, initiated by grinding [2], Nitrides are reported made from the thermally initiated reaction of sodium azide with metal halides, a very large sealed ampoule is counselled to contain the nitrogen [3],... 

The filled skutterudite antimonides appear to represent excellent examples of electron-crystal, phonon-glass materials. The incoherent rattling of the loosely bound lanthanide atoms in these materials is inferred from the large values of the ADP parameters obtained in single-crystal structure refinements. This rattling lowers the thermal conductivity at room temperature to values within two to three times Km... 

This chapter presents a review of the current data on phase diagrams and crystal structures of binary, ternary and quaternary metal antimonides with the R elements (R = Sc, Y and the lanthanides).
