Figure 1
The structure of (NH4)2Ge[6][Ge[4]6O15] projected onto the ab plane showing the Ge—O network formed by Ge[4] (yellow spheres) and O atoms (small red spheres). The Ge[4]—O bonds are drawn with black lines. The octahedrally coordinated Ge[6] atoms are represented by dark blue spheres. They are linked with red lines to six Ge[4] atoms. Lilac spheres represent the N atoms of NH4+ cations. The H atoms have been omitted. |
