Projections of the crystal structure of Cs0.90Li2.88Rb0.22(SO4)2 along the (a) b and (b) a axis. Large, medium and small spheres represent Rb, Cs and Li atoms, respectively. The small spheres become darker, indicating different Li-atom positions (from 1 to 3). The dashed lines show the pseudo-hexagonal network. |
