Die Kristallstruktur von [(CH3)4N]2TeCl6 und über die Einschlußverbindung [(CH3)4N]2(CH3CN)TeCl6

Abriel, Walter (Berlin : De Gruyter, 1986)

Both title compounds show an antifluorite-like arrangement of (CH3)4N+ cations and TeCl6 2- anions. The remaining octahedral holes in this array can be filled with CH3CN molecules forming the inclusion compound by ...
Die Kristallstrukturen von Verbindungen des Typs A2TeX6 (A = K, NH4, Rb, Cs; X = Cl, Br, I)

Abriel, Walter; du Bois, André (Berlin : De Gruyter, 1989)

With the determination of the crystal structure of (NH4)2TeI6 the list of the descriptions of A2TeX6 structures is further completed. At 293 K three structure types are observed with an antifluorite packing of cations and ...
Über hexakoordinierte gemischte Halogeno-Anionen des Te(IV): Kristallographische und Raman-spektroskopische Untersuchungen an Rb2TeBr3, 5Cl2, 5

Abriel, Walter; Ehrhardt, Hartmut (Berlin : De Gruyter, 1988)

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 ...
Vibronische Kopplung und dynamisch verzerrte Strukturen in Hexahalogenotelluraten(IV): Ergebnisse aus Tieftemperatur-Röntgenbeugungsuntersuchungen (300—160 K) und aus FTIR-spektroskopischen Experimenten (300—5 K) [1]

Abriel, Walter; Zehnder, Ernst-Jürgen (Berlin : De Gruyter, 1987)

From theoretical considerations a dynamically distorted octahedron as a result of vibronic coupling between the ground state and the first excited state should exist for 14 electron AX6E systems like TeX62- . A high symmetry ...
Zur Stereochemie des freien Elektronenpaares in Verbindungen des vierwertigen Tellurs: Verzerrtes TeCI62-Oktaeder in [H3N(CH2)3NH3TeCI6 regulär oktaedrisches Anion in H3N(CH2)3NH3SnCI6

Abriel, Walter; Friedrich, Claudia (Berlin, Boston : De Gruyter, 1985)

Using 293 K diffractometer intensity data, the structures of [H3N(CH2)3NH3]TeCl6 and [H3N(CH2)3NH3]SnCl6 have been determined by single crystal X-ray technique and refined to a final of 0.027 and 0,029, respectively. The ...
