Description

Three new modifications of GdYbS3 can be retained metastably, after quenching from high pressure and temperature. The Guinier powder data is presented and indexed. The three modifications include a cubic defect Th3P4-type phase with a = 8.310(2) A, an orthorhombic A-type phase with a = 7.279(4) A, b = 15.119(6) A and c = 3.875(3) A, and an orthorhombic U2S3-type phase with a = 10.603(5) A, b = 3.869(3) A and c = 10.385(5) A. Structural relationships between the present group of structures and the structures of the rare earth sulfides with formula Ln2S3 are discussed. (orig.)

Drei neue Modifikationen von GdYbS3 koennen nach Abschrecken von hohem Druck und hoher Temperatur metastabil zurueckgehalten werden. Die Guinier-Daten werden vorgelegt und die Indizes bestimmt. Zu den drei Modifikationen gehoeren eine Phase vom Typ Th3P4 mit kubischen Defekten mit a = 8.310(2) A, eine orthorhombische Phase vom Typ A mit a = 7.279(4) A, b = 15.119(6) A und c = 3.875(3) A, und eine orthorhombische Phase vom Typ U2S3 mit a = 10.603(5) A, b = 3.869(3) A und c = 10.385(5) A. Die strukturellen Beziehungen zwischen dieser Gruppe von Strukturen und den Strukturen seltener Erdsulfide der Formel Ln2S3 werden diskutiert. (orig./AK)
