 Title    Preparation and Crystal Structure of the High Pressure Phase Tm 2 S3-II  
 Abstract    Single crystals of the quenchable high pressure phase Trri2S3-II were grown from a TmJ3-flux at 10 kbar, 1600 °C. The crystals are monoclinic, space group P2i/m, with a = 11.110(5) A, 6 = 3.874(3) A, c = 10.872(5) A, ß = 108.88(2) ° and Z = 4. In Tm2S3-II, which is isotypic with Er3ScS6, the four independent thulium atoms are coordinated by six (2 x), seven and eight sulfur atoms.

 Title    Hochdruckmodifikationen der Lanthaniden(III)sulfide Ln2S3  
 Abstract    (L n = Lu-H o, Y) mit U 2S3-Struktur High Pressure Modifications o f the Rare Earth Sulfides L n 2S3 (Ln == Lu-Ho, Y) with U 2S3-Structure K l a u s -J ü r g e n R a n g e u n d R i c h a r d L e e b Rare New modifications of the rare-earth sesquisulfides Ln2S3 (Ln = L u -H o, Y) were found after high pressure, high temperature treatment and quenching to ambient condi­ tions. The crystal structure of the prototype Tm2S3-III was determined from single­ crystal data. Tm 2S3-III and the other members of the isotypic series Ln2S3-III are iso-structural with U 2S3. Some relations between the U 2S3 structure and other structures with trigonal prismatic anion configurations are discussed.

 Title    Crystal Structures of the High Pressure Phases ZnAs and CdAs  
 Abstract    The structure of the high pressure compounds ZnAs and CdAs have been determined using Guinier film and counter methods. The compounds are orthorhombic, (space group Pbca; Z = 8), with a = 5.679(2) A, 6 = 7.277(4) A, c = 7.559(4) A and a = 5.993(4) Ä, b = 7.819(6) A,c = 8.011(6) A respectively. ZnAs and CdAs are isostructural with the normal pressure phases ZnSb and CdSb, which are related to the high pressure phase Si III. Structural relationships are discussed includ-ing the Si Ill-diamond structure relationship.
