35Cl NQR and X-Ray Studies of Hexachloropalladates A2PdCl6 (A = Rb, Cs, NH4) and the Cl2 – Clathrates Bis(tetramethylammonium)hexachloropalladate (Me4N)2PdCl6 · Cl2 and Bis(tetramethylammonium)hexachlorostannate (Me4N)2SnCl6 · Cl2

Abstract

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.
