The 35Cl NQR frequencies of A2PdCl6 were studied. For A = (CH3)4N+ a clathrate [(CH3)4N]2PdCl6 · Cl2 was found and its crystal structure was determined (Fd3 c, Z = 32, a = 2554.5 pm, R = 0.062). The clathrate [(CH3)4N]2SnCl6 · Cl2 was prepared, too. It is isomorphous with the corresponding palladium salt. The results of the 35Cl NQR studies are discussed on the basis of the crystal structure.

The self-exchange velocity (SEV) of neighboring unlike ions, has been evaluated by molecular dynamics simulations of molten CsCl, (Li, K)C1 and (Li, K, Cs)Cl at 673 K. From the increase of the SEV's in the same order as the internal mobilities it is conjectured that there is a strong correlation between these two properties. The pair correlation functions, and the self-diffusion coefficients and the SEV's of Li+, K+, and Cs+ with reference to Cl- have also been calculated. The results allow to conclude that the self-exchange velocity of the cations become vCs < vK < vLi at xCs =0.1 and vLi < vK < vCs at xCs > 0.4. The sequence of the self-diffusion coefficients agrees with that of the SEV's. The results enable to conclude that it is possible to enrich Cs at up to xCs ~ 0.3 - 0.4 in the molten LiCl-KCl eutectic system.

Abstract(NH4)2[V(NH3)Cl5] kristallisiert ebenso wie [Rh(NH3)5Cl]Cl2 orthorhombisch in der Raumgruppe Pnma mit Z = 4. Die Verbindungen sind aus isolierten NH4+‐ bzw. Cl−‐und komplexen MX5Y‐Ionen aufgebaut, in denen folgende Abstände beobachtet werden. VN: 213,8, VCl: 235,8–239,1, RhN: 207,1–208,5 207,1–208,5 RhCl: 235,5 pm. Beide Strukturen unterscheiden sich vom K2PtCl6‐Typ im wesentlichen nur durch den geordneten Einbau der MX5Y‐Polyeder. Die Verbindungen M2Vcl6 und M2VOCl5 mit M = K, NH4, Rb und Cs kristallisieren mit Ausnahme des orthorhombischen K2VOCl5 im K2PtCl6‐Typ. Der geordnete Einbau der MX5Y‐ Ionen im (NH4)2[V(NH3)Cl5], [Rh(NH3)5Cl]Cl2 und K2VOCl5 ermöglicht eine dichtere Packung.
