- Structure refinement of potassium periodate at 297 and 150 K
-
The scheelitetype structure of potassium periodate, KIO4, has been confirmed and refined from single-crystal X-ray data at two temperatures. The compound crystallizes tetragonally, space group I41/a, with a = 5.726(1), c = 12.607(4) ? at 297(1) K. and a = 5.704(3), c = 12.478(8) ? 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.
