Figure 2
Representation of the polyhedral cages in (a) Rb_7.39(3)Eu_0.61(3)In_8.88(5)Ge_37.12(5), (b) Rb_6.30(3)Eu_1.70(3)In_9.76(4)Ge_36.24(4), and (c) Rb_6.24(2)Eu_1.76(2)In_10.16(5)Ge_35.84(5). The anisotropic displacement parameters are drawn at the 95% probability level. In the electronic version of the paper, the framework sites are color coded as follows: 6c is light blue, 16i is dark blue, and 24k is shown in black. The Rb and Eu atoms co-occupying site 2a are shown in purple and the Rb at site 6d are drawn in yellow.
