| Strukturverfeinerung von Rubidiumperrhenat bei 297 und 159 K Structure Refinement of Rubidium Perrhenate at 297 and 159 K  | | | Abstract
| The scheelite-type structure of rubidium per rhenate, R b R e 0 4, has been confirmed and refined from single-crystal X-ray data at two tempera tures. The com pound crystallizes tetragonally, space group I4,/a, with a = 5,8401(5), c = 13,265(2) A at 297(1) K, and a = 5,8289(7), c = 13,109(2) A at 159(3) K, respectively. Except for a significant decrease in the anisotropic displace ment factors, the changes in the structural para meters at low temperature are rather small.

| Structure Refinem ent o f Potassium Periodate at 297 and 150 K  | | | Abstract
| The scheelitetype structure of potassium perio date, K I 0 4, has been confirmed and refined from single-crystal X-ray data at two temperatures. The compound crystallizes tetragonally, space group 14,/a, with a = 5.726(1), c = 12.607(4) Ä at 297(1) K, and a = 5.704(3), c = 12.478(8) A at 150(1) K, respectively. Except for a significant decrease in the anisotropic displacement factors, the changes in the structural parameters at low temperature are rather small. | | |
