Description / Table of Contents:
Rb2PbO3 [single crystals, 244 (hkl)] crystallises orthorhombic [D2h16—Pmcn] with a = 10.8, b = 7.49, c = 5.98 Å [Z = 4, dpyk = 5.69, drö = 5.80 g · cm-3], Rb in 8(d) Pb in 4 (c), OI in 4 (c). The parameters are shown in table 2. The MADELUNG Part of Lattice Energy of Rb2RBO3 and structurally related models are calculated and discussed in detail.Characteristic for the structure are ldimensional chains consisting of alternatingly directed pseudo-tetragonal pyramids, ∞1[PbO1O4/2], connected via common basis edges.

Rb2PbO3 [Einkristalle, 244 (hkl)] kristallisiert orthorhombisch [D2h16 — Pmcn] mit a = 10,8, b = 7,49, c = 5,98 Å [Z = 4, dpyk = 5,69, drö = 5,80 g · cm-3]. Rb in 8 (d), Pb in 4 (c), OI in 8 (d) und OIIin 4 (c), bez. der Parameter vgl. Tab. 2. Der MADELUNG-Anteil der Gitterenergie wird für Rb2PbO3 und strukturell ähnliche Modelle berechnet und ausführlich diskutiert.Strukturcharakteristisch sind ldimensionale Ketten von alternierend ausgerichteten, basiskanten-verknüpften pseudotetragonalen Pyramiden ∞1[PbO1O4/2].
