摘要：

Single crystals of sodium metaperrhenate, NaReO4, have been obtained by oxidation of rhenium metal with sodium nitrate under high pressure-high temperature conditions (modified Belt-type apparatus, 4 kbar, 400 degrees C, Au-capsules). The crystals are tetragonal, space group I4(1)/a, with a = 5.3654(4). c = 11.732(2) Angstrom and Z = 4. The structure was refined to R = 0.026, R(w) = 0.013 for 382 unique, absorption-corrected reflections. The scheelite-type structure for NaReO4, proposed by Beintema in 1937, could be confirmed. It consists of isolated ReO4 tetrahedra (Re-O = 1.728(2) Angstrom), connected by NaO8 dodecahedra ([Na-O] = 2.582(2) Angstrom).
