    Description / Table of Contents: Preparation and Crystal Structure of KSbS2Red KSbS2 was prepared in a aqueous solution of KHS and Sb2S3 under mild hydrothermal conditions. For crystallographic data see „Inhaltsübersicht“. There are SbS2--chains, built up by ψ-trigonal bipyramids, which are connected by sharing edges. The K+-Ions between these chains have a nearly octaedric coordination.
    Notes: Rotes KSbS2 wurde aus wässerigen Lösungen von KHS und Sb2S3 unter milden hydrothermalen Bedingungen dargestellt und strukturell untersucht. Die kristallographischen Daten sind: monoklin, Raumgruppe C2/c—C2h6 a = 8,75 ± 0,01 Å, b = 8,98 ± 0,01 Å, c = 6,84 ± 0,01 Å β = 121,6° ± 0,1 4 Formeleinheiten in der Elementarzelle. Nach der vollständigen röntgenographischen Strukturaufklärung liegen SbS2--Kettenanionen vor, die aus über Kanten verknüpften ψ-trigonalen Bipyramiden aufgebaut sind. Zwischen diesen Ketten sitzen die Kaliumionen mit einer nahezu oktaedrischen Koordination.

    Description / Table of Contents: On Alkali Beryllium Phosphates NaBePO4, KBePO4 and RbBePO4 were prepared by reaction of alkali polyphosphate with Be(OH)2 in the corresponding molten alkali sulfate. NaBePO4 is identical with the natural Beryllonit. KBePO4 and RbBePO4 are isotypic to the NH4LiSO4 structure. In the structure of KBePO4 there is a three-dimensional net of PO4 and BeO4 tetrahedra connected by common corners. For crystallographic data see “Inhaltsübersicht” and Tab.2.
    Notes: NaBePO4, KBePO4 und RbBePO4 lassen sich in den entsprechenden Alkalisulfatschmelzen durch Umsatz der Alkalipolyphosphate mit Be(OH)2 darstellen. Das NaBePO4 entspricht dem natürlich vorkommenden Beryllonit, während KBePO4 und RbBePO4 isotyp zum NH4LiSO4 kristallisieren. Die vollständige röntgenographische Strukturbestimmung des KBePO4 zeigte, daß ein Raumnetzverband von eckenverknüpften PO4- und BeO4-Tetraedern vorliegt. Die Kristallographischen Daten sind: orthorhombisch, Pna21, a = 8,30 ± 0,02 Å, b = 8,47 ± 0,02 Å, c = 5,00 ± 0,02 Å. Atomlagen vgl. Tab.2.

    Description / Table of Contents: Preparation and Crystal Structure of SrCu2Sb2 and SrZnBi2SrCu2Sb2 and SrZnBi2 have been prepared and analytically and structurally characterized. SrCu2Sb2 crystallizes tetragonal in the CaBe2Ge2 structure type. SrZnBi2 has its own structure type. In both structures the transition metal atoms form with the semimetal atoms tetragonal pyramids, which are connected by common edges of the basis to twodimensional sheets. These sheets are separated in the case of SrCu2Sb2 by single sheets of strontium atoms, in the case of SrZnBi2 by double sheets of strontium atoms in which fourfold nets of Bi atoms are located.
    Notes: SrCu2Sb2 und SrZnBi2 wurden dargestellt, analytisch und strukturell charakterisiert.SrCu2Sb2 kristallisiert tetragonal (a = 4,51 ± 0,01 Å, c = 10,91 ± 0,02 Å, Raumgruppe P4/nmm, z = 2) im CaBe2Ge2-Typ. SrZnBi2 kristallisiert in einem eigenen Strukturtyp (tetragonal, a = 4,64 ± 0,01 Å, c = 21,96 ± 0,03 Å, Raumgruppe I4/mmm, z = 4). In beiden Strukturen bilden die Übergangsmetalle mit den Halbmetallen zweidimensional unendliche Pyramidenschichten aus, die im Falle des SrCu2Sb2 durch Erdalkalieinfachschichten, im Falle des SrZnBi2 durch Erdalkalidoppelschichten mit eingelagerten Bi-Vierecknetzen getrennt sind.

    Description / Table of Contents: Crystal Chemistry of the Alkali Salts of the Main Group V Element TetrathioacidsThe anhydrous tetrathioantimonates of K+, NH4+, and Na+ crystallize cubic in the (NH4)3SbS4-structure type. The analogous tetrathioarsenates and -phosphates form the (NH4)3AsS4-structure type. In the formation of these two different structures the density of the atomic packing is essential.
    Notes: Die wasserfreien Tetrathioantimonate von K+, NH4+ und Na+ kristallisieren kubisch im (NH4)3SbS4-Typ, während bei den bisher bekannten Alkalitetrathioarsenaten und -phosphaten der (NH4)3AsS4-Typ beobachtet wird. Die Ausbildung der beiden unterschiedlichen Strukturtypen wird auf Packungseffekte zurückgeführt.
