Figure 2
Comparison of the one-dimensional M/Te chains of (a) K4Hf3Te17, (b) Cs4Zr3Te16 and (c) Rb4Zr3Te16 with shaded circles for Zr and open circles for Te atoms, black lines for Te—Te single bonds and broken lines for longer Te⋯Te interactions of less than 3.2 Å. The atom-numbering scheme for Rb4Zr3Te16 is given; symmetry codes are as in Table 1. |
