Abstract: | On the Synthesis and Crystal Structure of Ba6Lu4Zn10O22 with OBa6] Octahedra Single crystals of Ba6Lu4Zn10O22 have been prepared by high temperature reactions and investigated by X-ray techniques. This compound is isotypic to Ba3In2Zn5O11 and the first member of the Rare Earth elements. Ba6Lu4Zn10O22 crystallizes with cubic symmetry, space group T -F4 3m, a = 13.452(1) Å and Z = 4. Zn2+ shows a tetrahedral, Lu3+ an octahedral and Ba2+ a three-fold capped trigonal prismatic coordination by O2?. The ZnO4 tetrahedra and LuO6 octahedra are forming macro polyhedra of the type Zn10O20 and Lu4O16. A discussion is given for the Ba6O33 and Ba6O42 groups. |
