| 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). | | | |
