Abstract: | Gold-rich Aurides with Caesium: Cs1.34Rb0.66RbAu7 and Cs1.60Rb0.40RbAu7 Cs1,60Rb0,40RbAu7, Raumgruppe Cmmm, Z = 2, a = 5,677(1) Å, b = 13,273(3) Å, c = 7,288(1) Å, R1/wR2 = 0,0392/0,0892, Z(F) ≥ 2σ(F) = 700 and Z(Var.) = 23. Silver coloured, brittle single crystals of Cs1.34Rb0.66RbAu7 and Cs1.60Rb0.40RbAu7 were obtained by the reaction of CsN3, RbN3 and gold sponge at 903 K. The structures were determined from X-ray single-crystal diffractometry data: Cs1.34Rb0.66RbAu7, space group Cmmm, Z = 2, a = 5.657(1) Å, b = 13.265(4) Å, c = 7.281(2) Å, R1/wR2 = 0.0373/0,0628, N(F) ≥ 2σ(F) = 818 and N(var.) = 23. |
