Figure 2
The structures of layers in the CuSb and ZnAs phases, showing (a) CuSb-I, (b) CuSb-II, (c) ZnAs-I and (d) ZnAs-II. The figures are projected down the axis that best highlights their similarity to CdCl2. The colours in parts (a) and (b) are as in Fig. 1[link]. In parts (c) and (d), Zn polyhedra are shown in blue and As in yellow. XeF2 ligands are shown in `stick' format.
