- W1972396765 abstract "Durch Umsetzung von Rubidium- und Caesiumacetylid mit Palladium- bzw. Platinpulver in abgeschmolzenen Glasampullen konnten bei 653 K ternäre Acetylide der Zusammensetzung A2MC2 (A = Rb, Cs; M = Pd, Pt) erhalten werden. Ihre Kristallstrukturen wurden auf Grundlage von Röntgenpulveruntersuchungen gelöst und verfeinert (Na2PdC2-Typ, P 3 m1, Z = 1). Die Strukturen sind durch [M(C2)2/22–]-Ketten charakterisiert, die von den Alkalimetallionen separiert werden. Ramanspektroskopische Untersuchungen ergaben Wellenzahlen zwischen 1833 und 1842 cm–1 für die C–C-Streckschwingungen, die sehr gut mit den Frequenzen in den analogen Natrium- und Kaliumverbindungen übereinstimmen. Ternary Alkali Metal Transition Metal Acetylides A2MC2 with A = Rb, Cs, and M = Pd, Pt By the reaction of Rb2C2 and Cs2C2 with palladium or platinum powder in sealed glass ampoules at 653 K ternary acetylides A2MC2 (A = Rb, Cs; M = Pd, Pt) were obtained. Their crystal structures were solved and refined by means of X-ray powder investigations (Na2PdC2 structure type, P 3 m1, Z = 1). The crystal structures are characterised by [M(C2)2/22–] chains separated by the alkali metals. Raman spectroscopic investigations revealed wave numbers of the C–C stretching vibrations between 1833 and 1842 cm–1, which are in good agreement with the results of the analogous sodium and potassium compounds." @default.
