AbstractThe scheelite-type structure of rubidium perrhenate, RbReO4, has been confirmed and refined from single-crystal X-ray data at two temperatures. The compound crystallizes tetragonally, space group I41/a,with a = 5,8401(5), c = 13,265(2) Å at 297(1) K, and a = 5,8289(7), c = 13,109(2) Å at 159(3) K, respectively. Except for a significant decrease in the anisotropic displacement factors, the changes in the structural parameters at low temperature are rather small.
