    Description / Table of Contents: A cubic, As-containing modification of Al2S3 has been prepared by reaction of Al + As + 4 S.Crystallographic data: cubic, a = 9.93 ± 0.01 Å; Fd3m - 07h; d20°C = 2.80 g/cm3, dx = 2.78 g/cm3.Atomic positions: 32 S atoms in 32e with x = 3/8; 16 Al-atoms in 16c; 5.33 Al atoms statistically in tetrahedral positions (8b).
    Notes: Versuche zur Darstellung von AlAsS4 lieferten statt der gesuchten Verbindung hexagonales Al2S3, wenn AlAs mit Schwefel umgesetzt wurde. Aus einem stöchiometrischen Gemenge von Al, As und 4 S dagegen bildete sich ein bisher unbekanntes, kubisches Al2S3. in dem etwa 2 Atom%% Al durch As ersetzt sind.Kristallographische Daten: Kubisch  -  Raumgruppe Fd3m  -  O7h; a = 9,93 ± 0,01 Å; d20°C = 2,80 g/cm3; dx = 2,78 g/cm3.Punktlagen: 32 Schwefelatome in 32e mit x = 3/8; 16 Aluminiumatome in Oktaederlücken (16c) bei 1/8 1/8 1/8 und 5,33 Aluminiumatome statistisch in Tetraederlücken (8b) bei 1/2 1/2 1/2.

    Description / Table of Contents: The crystal structures of BaSi2, SrSi2 and of a new modification of CaSi2 are described. The Si arrangements in these structures are discussed. There are Si4 tetrahedrons in BaSi2, a Sin threedimensional framework in SrSi2 and twodimensional corrugated sheets of Si hexagons in CaSi2.
    Notes: Die Kristallstrukturen von BaSi2 und SrSi2 werden beschrieben. Von CaSi2 wurde eine neue Modifikation aufgefunden. Die in den 3 Phasen nachgewiesenen Si-Verbände (Si4-Tetraeder im BaSi2, Sin-Raumnetzgerüst im SrSi2 und Sin-Schichten im CaSi2) werden vergleichend diskutiert.

    Description / Table of Contents: The ternary disilicides of group-II elements Ca1-xSrxSi2 und Sr1-xBaxSi2 are prepared and crystallographically investigated. In the quasibinary system CaSi2—SrSi2 the structures of the Ca-rich phases can be described as stacks of twodimensional corrugated sheets of Si hexagons. The phases Sr1-xBaxSi2 with X = 0.2 to X = 1.0 crystallize in the structure type of BaSi2 with isolated Si4 tetrahedrons. There in no miscibility between CaSi2 and BaSi2 in the solid phase.
    Notes: Die ternären Erdalkalidisilicide der Stöchiometrie Ca1-xSrxSi2 und Sr1-xBaxSi2 wurden dargestellt und röntgenographisch charakterisiert. Im quasibinären Schnitt CaSi2—SrSi2 wurden im Ca-reichen Teil Phasen erhalten, deren Strukturen sich als Stapelvarianten mit zweidimensionalen, gewellten Si-Sechsecknetzen erwiesen. Im System Sr1-xBaxSi2 tritt der Strukturtyp des BaSi2 mit isolierten Si4-Tetraedern von x = 0,2 bis x = 1,0 auf. Der quasibinäre Schnitt BaSi2—CaSi2 entspricht dem Zustandsdiagramm eines Zweistoffsystems ohne Mischkristallbildung.

    Description / Table of Contents: On the Structural Chemistry of BaMg2X2 (X = Si, Ge, sn, Pb)The new compounds BaMg2X2 (X = Si, Ge, Sn, Pb) have been prepared and their structures have been determined. BaMg2Si2 and BaMg2Ge2 crystallize in the ThCr2Si2-type, BaMg2Sn2 and BaMg2Pb2 show two new atomic arrangements, which are layer variants of the former type.
    Notes: Die Verbindungen BaMg2X2 (X = Si, Ge, Sn, Pb) wurden dargestellt und strukturell untersucht. BaMg2Si2 und BaMg2Ge2 kristallisieren im ThCr2Si2-Typ während BaMg2Sn2 und BaMg2Pb2 jeweils neue Strukturtypen ausbilden. Diese lassen sich aber als Schichtvarianten an den ThCr2Si2-Typ anschließen.

    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.
