Englische Kurzfassung:
The new compounds CsAu3S2, RbAu3Se2 and CsAu3Se2 were prepared by high temperature reactions. They are isostructural and crystallize in P`3m1, Z=1 with a=6.192(1)Ä, c=5.080(2)Ä for CsAu3S2, a=6.112(4)Ä, c=5.224(6)Ä for RbAu3Se2 and a=6.281(1)Ä, c=5.205(1)Ä for CsAu3Se2. Their crystal structures were determined by single crystal diffractometer data. They are characterized by the formation of corrugated chalcogenoaurate layers 2-oo-[Au3Q2](-) seperated by the alkali cations. Au is in a strictly linear coordination (d(Au-S) 2.32Ä, d(Au-Se) 2.450(7)Ä and 2.434(4)Ä respectively), the bond angles of the chalcogens are close to 80?. The shortest Au-Au distances (3.056(2)Ä) occur in the rubidium compound. The crystal structures are related to the CsCu3S2 type.
