Über hexakoordinierte gemischte Halogeno-Anionen des Te(IV): Kristallographische und Raman-spektroskopische Untersuchungen an Rb2TeBr3,5Cl2,5 / On Hexacoordinated Mixed Halogeno Anions of Te(IV): Crystallographic and Raman Spectroscopic Investigation of Rb2TeBr3,5Cl2,5

Abstract

Abstract The title compound contains the anions [TeBr3Cl3]2- and [TeBr4Cl2]2- in a 1:1 ratio. The corresponding point symmetries, detected by Raman spectroscopic methods, are 3 m and 4/mmm, respectively. The crystal structure analysis exhibits a random distribution of these anions: K2PtCl6- type, space group Fm3̅m with a = 10.4602(5) Å and Z = 4, final R = 0.036 from 178 F0 (MoKα).
