Figure 2
(a) A representation of the Sm5−xLixGe4 structure, viewed approximately down the [100] direction. The rare earth metals are shown as large spheres (green in the electronic version of the paper), Ge atoms as medium spheres (orange) and Li atoms as small spheres (blue). (b) A representation of the first building unit, comprising a trigonal prism (shaded; orange in the electronic version) and a parallelepiped (hollow framework of rare earth metals). (c) A view of the chain of vertex/edge-shared penta­gonal rings built by Li atoms and Ge—Ge dimers.
