Table 1. Selected bond lengths (Å) in related garnet-type Na3Te2(ZO4)3 oxidotellurates(VI) and their structure similarity parameters relative to Na3Te2(FeO4)3 .
| Na3Te2(FeO4)3 | Na3Te2[(Al,Fe)O4]3 | Na3Te2(GaO4)3 | |
|---|---|---|---|
| Na1—O1 (4×) | 2.4208 (10) | 2.396 (3) | 2.3907 (17) |
| Na1—O1 (4×) | 2.6226 (10) | 2.597 (3) | 2.5609 (17) |
| Te1—O1 (6×) | 1.9169 (9) | 1.914 (2) | 1.9124 (17) |
| M1—O1 (4×) | 1.8680 (9) | 1.829 (2) | 1.8405 (16) |
| Degree of lattice distortion, S | 0.0064 | 0.0079 | |
| Atomic displacement of O1 a (Å) | 0.0205 | 0.0322 | |
| Measure of similarity, Δ | 0.001 | 0.002 |
Note: (a) The three other atomic sites do not show a displacement due to their site symmetries.
