Figure 9
Stereopair of the unit cell of Sr3Ge2N4 showing the zigzag chains formed by the Ge2− anions in the form of an extended Ψ-Se Zintl polyanion. The second Ge atom (gray spheres) also converted into Ψ-Se together with the N atoms (blue spheres), converted into Ψ-O, form molecules of Ψ-SeO2, similar with those occurring in real SO2. The Sr atoms have been omitted. |
