Figure 4
Cronstedtite-1M, projection along −c* (monoclinic indexing) shown from the side of the Tet sheet (from the `bottom side'). The c vector is oriented from the observer. Three consecutive 1:1 layers (in different colours, for the sake of better recognition) are displayed, and the layers close to the observer are stepwise partially removed in order to demonstrate the stacking rule and sequence. The O4 atoms (apical to the Tet sheet) are in this projection `hidden' behind the T1 atoms. |
