Figure 2
Projections of the crystal structure of Cs1.15Li2.85(SO4)2 along the (a) b and (b) a axis. Large, medium and small spheres represent Cs2, Cs1 and Li atoms, respectively. The small spheres become darker, indicating different Li-atom positions (from 1 to 4). The dashed lines show the pseudo-hexagonal network. The atomic coordination of (c) S1 and (d) S2 is also shown. |
