Pb3Te2O6Br2
Single crystals of the title compound, trilead(II) bis[tellurate(IV)] dibromide, have been grown under hydrothermal conditions. The structure is isotypic with that of the chloride analogue, Pb3Te2O6Cl2, and consists of three Pb, two Te, two Br and four O atoms in the asymmetric unit. Except for two...

Single crystals of the title compound, trilead(II) bis[tellurate(IV)] dibromide, have been grown under hydrothermal conditions. The structure is isotypic with that of the chloride analogue, Pb3Te2O6Cl2, and consists of three Pb, two Te, two Br and four O atoms in the asymmetric unit. Except for two of the O atoms, all atoms are located on mirror planes. The Pb3Te2O6Br2 structure can be described as being built up from ∞2[Pb3Te2O6]2+ layers extending parallel to (20overline{1}) and Br− anions between the layers. Cohesion of the structure is accomplished through Pb—Br contacts of two of the three lead atoms, leading to highly asymmetric coordination polyhedra. The lone-pair electrons of both TeIV and PbII atoms are stereochemically active and point towards the anionic halide layers. |
