    Description / Table of Contents: Preparation and Crystal Structure of RbLiSeRbLiSe is in the system Rb2Se/Li2Se the only ternary phase without mixed crystals of the binary compounds. The single crystal X-ray investigation of this yellow hygroscopic compound leads to the tetragonal space group P4/nmm (Z = 2) with the lattice constants a = 461.6(1) and c = 748.2(3) pm. Its crystal structure confirms a simple rule of expected structure types for inter alkali metal chalcogenides of the general formula ABX.
    Notes: Im System Rb2Se/Li2Se wurde RbLiSe als einzige Phase gefunden. Mischkristallbildung konnte nicht beobachtet werden. Die gelbe, sehr hygroskopische Verbindung kristallisiert nach Einkristalluntersuchungen tetragonal in der Raumgruppe P4/nmm (Z = 2) mit den Gitterkonstanten a = 461,6(1) und c = 748,2(3) pm. Als Vertreter des anti-PbFCl-Strukturtyps befolgt RbLiSe eine von uns empirisch ermittelte „Regel“ zur Struktursystematik der ternären Interalkalimetallchalkogenide des Formeltyps ABX.
