    Description / Table of Contents: Layered Structures of Ternary Chalcogenides A2M3X4 (A ≙ K, Rb, Cs; M ≙ Ni, Pd, Pt; X ≙ S, Se)The ternary chalcogenides A2M3X4 have been prepared by fusion reactions of alkali carbonates with metals M ≙ Ni, Pd or Pt and the chalcogens X ≙ S or Se. Alternatively, the chalcogenides could be synthesized from alkali carbonates and M in a stream of hydrogen charged with chalcogen. X-ray investigations on powdered samples and single crystals reveal layered structures in which neutral A2M3X4-slabs from stacking variants.
    Notes: Die Synthese ternärer Chalkogenide A2M3X4 gelang über Schmelzreaktionen durch Umsetzungen von Alkalimetallcarbonaten mit den Metallen M ≙ Ni, Pd oder Pt und den Chalkogenen X ≙ S oder Se oder über eine Reaktion der beiden erstgenannten Komponenten in einem mit Chalkogen beladenen Wasserstoffstrom.Röntgenographische Untersuchungen an pulverförmigen Proben sowie an Einkristallen führten zu Schichtstrukturen, in denen neutrale A2M3X4-Schichtpakete Stapelvarianten erzeugen.
