摘要：

By tempering powder samples (prepared from mixtures of binary oxides: Na2O2/ReO2 and Na2O/ReO3 respectively, Na:Re = 3:1, Ar and O2 atmosphere respectively, 400-450-degrees-C, corundum boat) in a closed Ag cylinder (500-550-degrees-C, 10d) yellow single crystals of Na3ReO5, sensitive to moisture, were grown. The compound crystallizes trigonal, space group P3(1), P3(2) respectively, with a = 5.544(1), c = 13.580(7) angstrom, Z = 3, d(ro) = 4.62 g/cm3. The crystal structure [4-circle diffractometer data, 1 091 I0(hkl), AgK-alpha, R = 6.14, R(w) = 6.08%] is characterized by "isolated" bipyramids ReO5. Na+ ions are occupying all the tetrahedral (Na2, Na3) and octahedral (Na1) holes of the pseudocubic face centred (c/a = 2.441) Re part of the lattice; resulting in a Na3Re kation framework corresponding to the Li3Bi type of structure. Effective Coordination Numbers (ECoN), the Madelung Part of Lattice energy (MAPLE) and the charge distribution (CHARDI) are computed and discussed.
