    Description / Table of Contents: Compounds in the Systems Potassium(Rubidium)/Gold/Antimony: K3Au3Sb2, Rb3Au3Sb2, and K1,74Rb0,26RbAu3Sb2Brittle, silver coloured single crystals of K3Au3Sb2, Rb3Au3Sb2 and K1,74Rb0,26RbAu3Sb2 were obtainded by reaction of the alkali metal azides (KN3, RbN3) with gold and antimon powder at 550°C. The structures of the isotypic compounds (R3m, Z = 3) were determined by X-ray single-crystal diffractometer data: K3Au3Sb2, a = 6,198(2) Å, c = 21,520(5) Å, R/Rw (w = 1) = 0,046/0,058, Z(F02) ≥ 3σ(F02) = 175, Z(Var.) = 14; Rb3Au3Sb2, a = 6,443(3), c = 21,69(2), R/Rw (w = 1) = 0,059/0,082, Z(F02) ≥ 3σ(F02) = 258, Z(Var.) = 14; K1,74Rb0,26RbAu3Sb2, a = 6,288(2) Å, c = 21,617(5) Å, R/Rw (w = 1) = 0,049/0,069, Z(F02) ≥ 3σ(F02) = 390, Z(Var) = 14. The compounds crystallize with the K3Cu3P2-structure type. The Au—Sb partial structures consist of ∞2[AuSb2/3] layers with linear Sb—Au—Sb dumb-bells and SbAu3 pyramids. The layers are separated by two crystallographically independent alkali metal atoms along [001].
    Notes: Spröde, silberfarbene Einkristalle von K3Au3Sb2, Rb3Au3Sb2 und K1,74Rb0,26RbAu3Sb2 wurden durch Reaktion der Alkalimetallazide (KN3, RbN3) mit Gold- und Antimonpulver bei 550°C erhalten. Die Strukturen der isotypen Verbindungen (R3m, Z = 3) wurden aus Einkristall-Röntgen-Diffraktometerdaten bestimmt: K3Au3Sb2, a = 6,198(2) Å, c = 21,520(5) Å, R/Rw (w = 1) = 0,046/0,058, Z(F02) ≥ 3σ(F02) = 175, Z(Var.) = 14; Rb3Au3Sb2, a = 6,443(3), c = 21,69(2), R/Rw (w = 1) = 0,059/0,082, Z(F02) ≥ 3σ(F02) = 258, Z(Var.) = 14; K1,74Rb0,26RbAu3Sb2, a = 6,288(2) Å, c = 21,617(5) Å, R/Rw (w = 1) = 0,049/0,069, Z(F02) ≥ 3σ(F02) = 390, Z(Var) = 14. Die Verbindungen kristallisieren im K3Cu3P2-Typ. Die Au—Sb-Teilstruktur besteht aus ∞2[AuSb2/3]-Schichten mit linearen Sb—Au—Sb-Hanteln und SbAu3-Pyramiden. Die Schichten werden längs [001] durch zwei kristallographisch unterschiedliche Alkalimetallatome separiert.

    Description / Table of Contents: Single-Crystal Growth and Structure Refinement of RbAu and CsAuSingle-crystals of RbAu and CsAu were obtained by the reaction of the alkalimetal azides with gold-powder at 400°C. The structures were determined from X-ray single-crystal diffraktometer data: space group Pm3m, Z = 1; RbAu, a = 4.098(1) Å, R/Rw(w = 1) = 0.011/0.011, N(Fo2) ≥ 3σ(Fo2) = 41 and N(var.) = 4; CsAu, a = 4.258(1) Å, R/Rw(w = 1) = 0.009/0.010, N(Fo2) ≥ 3σ(Fo2) = 34 and N(var.) = 4. Both compounds crystallize in the completely ordered CsCl-type with neglible deviations from the ideal 1:1-composition.

Beide Verbindungen kristallisieren im vollständig geordneten CsCl-Typ mit vernachlässigbarer Abweichung von der idealen 1:1-Zusammensetzung.

    Description / Table of Contents: Na8Au11In6: a Gold Indium Polyhedra Framework with Pentagonal Bipyramidal AuAu5In Building UnitsSilver coloured, brittle single crystals of a hitherto unknown Na8Au11In6 were synthesized by the reaction of NaN3, indium and gold sponge at 500°C. The structure was determined from X-ray single-crystal diffractometry data: space group Pbcm, Z = 4, a = 5.483(1) Å, b = 25.663(2) Å, c = 15.046(5) Å, R1/wR2 = 0.036/0.087, Z(Fo2) = 3σ(Fo2) = 2584 and N(var.) = 125.Na8Au11In6 crystallizes in a new structure type. The gold indium partial structure contains tetrahedral [Au2AuIn]T and pentagonal bipyramidal [AuAu5In]PBP building units which are connected to a three-dimensional framework via Au In exo-bonds and bridging gold and indium atoms. The interconnection pattern of the polyhedra is described by the formula [Au2AuIn]TIn4/2i-iAu2aIn2a [AuAu5In]PBP according to the notation for transition metal clusters. The sodium atoms are placed in channel like cavities within the gold indium partial structure, which run along [100]. Structural relationships between Na8Au11In6 and Friauf Laves phases are discussed.
    Notes: Silberfarbene, spröde Einkristalle eines bislang unbekannten Na8Au11In6 wurden durch Umsetzung von NaN3, Indium und Goldschwamm bei 500°C erhalten. Die Struktur wurde aus Röntgen-Einkristall-Diffraktometerdaten bestimmt: Raumgruppe Pbcm, Z = 4, a = 5,483(1) Å, b = 25,663(2) Å, c = 15,046(5) Å R1/wR2 = 0,036/0,087, Z(Fo2) = 3σ(Fo2) = 2584 and Z(Var.) = 125.Na8Au11In6 kristallisiert in einem neuen Strukturtyp. Die Gold-Indium-Teilstruktur enthält tetraedrische [Au2AuIn]T- und pentagonal bipyramidale [AuAu5In]PBP-Baueinheiten, die über Au-In-exo-Bindungen und verbrückende Au- und In-Atome zu einem 3D-Polyedergerüst verbunden werden. Das Verknüpfungsmuster der Polyeder wird nach der Notation für Übergangsmetallcluster als [Au2AuIn]TIn4/2i-iAu2aIn2a [AuAu5In]PBP beschrieben. Die Natriumatome befinden sich in Kanälen der Au-In-Teilstruktur, die entlang [100] verlaufen. Strukturelle Beziehungen zwischen Na8Au11In6 und Friauf-Laves-Phasen werden diskutiert.
