    Description / Table of Contents: Preparation and Crystal Structure of Cu2SrSnS4Cu2SrSnS4 was prepared from a mixture of the three binary sulfides at 620-700° C. The structure analyses by single crystal X-ray investigations yields a trigonal C-symmetrie for the unit of the structure with a = 6.290 and c = 15.578 Å and three formula units. Space group: C32-P31 (No. 144). Copper and tin have tetrahedral surrounding of S2-. The neighbourhood of Sr2+ has the shape of a deformed archimedic antiprisma.
    Notes: Cu2SrSnS4 wurde aus einem Gemisch der drei binären Sulfide bei 620-700°C dargestellt. Die Strukturanalyse mit Einkristall-Röntgenbeugungsdaten ergab trigonale C-Symmetrie mit a = 6,29o und c = 15,578 Å und drei Formeleinheiten pro Elementarzelle. Raumgruppe: C32-P31 (Nr. 144). Kupfer und Zinn sind tetraedrisch von S2- umgeben. Das Sr2+ hat 8 nächste Schwefelnachbarn in der Anordnung eines verzerrten archimedischen Antiprismas.

    Description / Table of Contents: Experimental and X-ray Investigations of the System Cu2-xAgxBaSnS4A description of the preparation, properties and the x-ray investigations of Cu2BaSnS4 (A) and Ag2BaSnS4 (B) is given. (A) crystallizes trigonal. Space group: C32-P31, a = 6.367 and c= 15.833 Å. (A) is isotypic with Cu2SrSnS4 [1]. (B) has an orthorhombic unit cell: a = 7.127, b = 8.117, c = 6.854 Å. The x-ray investigation of the system Cu2-xAgxBaSnS4 (0 ≤ x ≤ 2) yields a homogenity range of (0 ≤ x ≤ 0.65) for (A) and for (B) (1.7 〈 x ≤ 2).
    Notes: Es wird über die Darstellung, die Eigenschaften und die röntgenographische Untersuchung von Cu2BaSnS4 (A) und Ag2BaSnS4 (B) berichtet. (A) kristallisiert trigonal,  -  Raumgruppe C32-P31 mit a = 6,367 und c = 15,833 Å  -  und ist mit Cu2SrSnS4 [1] isotyp. (B) hat eine orthorhombische Elementarzelle: a = 7,127, b = 8,117 und c = 6,854 Å. Die röntgenographische Systemuntersuchung an Cu2-xAgxBaSnS4 ( o ≤ x ≤ 2) ergibt die Phasenbreite: ( 0 ≤ x ≤ 0,65) für (A) und für (B) (1,7 〈 〈 x ≤ 2).
