Abstract

The oxyhalides Pb3TeO4X2 (X = Cl, Br, I) have been prepared from Pb3O2X2 and T6O2. All three compounds are isostructural and adopt the Nd2O2Te (PbBiO2I) structure type (14/m, Z = 1) according to single-crystal and powder X-ray and electron diffraction data. Contrary to previous results, the Pb/Te cation ordering was found to be nearly the same as Pb/I in schwartzembergite, Pb5IO4(OH)(2)Cl-3 but not Pb/Sb in nadorite PbSbO2Cl. We discuss the factors affecting Pb/M cation ordering in layered (Sillen-type) multinary oxyhalides of lead. (c) 2006 Elsevier SAS. All rights reserved.
