Zur Kristallstruktur von Li8PbO6 [1]

Abstract: Erstmals wurden farblose Einkristalle von Li8PbO6 durch Tempern inniger Gemenge von Na2PbO3 und Li2O [Ag‐Bömbchen, 650°C, 150 d] dargestellt und die Struktur bestimmt [382 I0(hkl), Vierkreisdiffraktometer PW 1100, ω/2Θ‐scan, MoKα, R = 3,07%, Rw = 3,00% in R3; a = 555,09(4), c = 1564,13(17) pm, drö = 4,28 g · cm−3, dpyk = 4,24 g · cm−3, Z = 3]. Die Struktur ist charakterisiert durch das Motiv einer hexagonal dichtesten O2−‐Packung, bei der die Hälfte aller Oktaederlücken mit Pb4+ und Li+ und die Hälfte aller Te… Show more

“…The first structure determination based on single-crystal structure data was published for Li 8 TbO 6 , followed by Li 8 SnO 6 4,5 and Li 8 PbO 6 , all of which crystallize in R 3̄. Hoppe and Wehrum 8 determined the structure of Li 7 TaO 6 using single-crystal data ( P 3, a = 5.358 Å, c = 15.073 Å, Z = 3), thus confirming the close structural relationship to Li 8 SnO 6 .…”

“…Alkali-metal salts of the hexaoxometalates have been known since their first mention by Scholder in 1958, who described compounds of the type Li 8 MO 6 (M = Sn, Pb, ,, Zr, , Hf 4 ). The most prominent characteristic of the powder diffraction patterns of Li 7 MO 6 (M = Nb, , Ta, ,− Sb, , Bi 7 ) and Li 8 MO 6 is their close resemblence, indicating that these compounds are isostructural.…”

“…Li 8 PbO 6 adopts the trigonal R3̅ H [148] space group. 12 Within the unit cell, Li occupies two symmetrically distinct Wyckoff positions, which are the tetragonally coordinated 18f sites and the octahedrally coordinated 6c sites. The O and Pb ions occupy the 18f and 3a Wyckoff positions, respectively.…”
