Cadmium binary structures

This applies to systems involving zinc or cadmium, on the one hand, and nitrogen or bismuth, on the other. For the remaining elements (Zn, Cd-P, As), the formation of solid solutions is most probable, owing to the strong interaction in the primary binary systems. The formation of variable phases based on antimony is predicted, but, because of the metastability of the binary compounds of the primary systems and also the absence of a structural analogy, the problem is complicated and requires a more detailed analysis. 

A similar relation is observed for the binaiy structure types YCde (SG.Im3,a = 1548.3 pm) (Larson and Cromer, 1971) and YbCdg (SG lm3, a = 1565.8 pm) (Palenzona, 1971), and temaiy YbAg2ln4 (Sysa et al., 1989). These structures are actually identical considering the lattice parameters, the space group symmetry, the sites, and the parameters of the atoms. In YbAg2ln4 the smaller silver and indium atoms are ordered, thus, it represents a temaiy ordered superstmcture of the binary ones. However, there is a difference between the binary compounds in YCdg one cadmium atom occupies the 24g site by about one third, and in...
