 Title    Präparative und röntgenographische Untersuchungen über Cäsium-Silber-Gold(III)-Chlorid Preparation and X-ray Investigations of Cesium Silver Gold(III) Chloride  
 Abstract    Cesium silver gold(III) chloride has been prepared from hydrochloric acid solutions. The composition of the preparations is variable and depends on the ratio [Au(III)]/[Ag(I)] in solution. It corresponds to the formula Cs2Agi_aAui+a;/3Cl6. In the range 0 < x < 0,64 six crystallographically different phases have been observed. Above x — 0,42 a cubic phase is obtained. The stoichiometric compound Cs2AgAuCl6 is obtained only from solutions with [Au(III)]/[Ag(I)] < 1. Reports in the literature which claim the stoichiometric compound Cs2AgAuCl6 to exist in a cubic and in a tetragonal form cannot be confirmed. Cs2AgAuCl6 crystallizes ortho-rhombically with the lattice constants a = 15,21 A, b= 15,16 A and c= 10,32 A (Z = 8).
