Figure 4
(a) Structure of GeIVPN3, projected on the ac plane, representing the chains of GeN6 octahedra that alternate with the zigzag tetrahedral chains (zweier), which are drawn solely in (b), intercalated with the Ge atoms. (c) The same structure projected onto the bc plane. The drawing represents only the chains of PN4 tetrahedra (Ψ-SO4). The P atoms are connected by black lines to show that the P(Ψ-S) atoms form chains similar to those of the real S atoms. (d) One isolated chain of PN4 tetrahedra shows its similarity with the chains represented in Fig. 5[link].
