Figure 4
(a) Projection of the structure on the ac plane, similar to that represented in Fig. 2[link](a). Here, some Ge[4]—Ge[4] contacts have been eliminated giving rise to a set of isolated blocks formed by Ge[6]Ge[4]6. Big dark blue spheres represent Ge[6] atoms. N atoms are represented as lilac spheres. (b) Perspective view of the two central blocks of (a). Red lines connect the Ge[6] atom to the six Ge[4] (Ψ-As) atoms. Yellow lines connect Ge[4] (Ψ-As) atoms.
