| 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. | | | |

| 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. | | | |

| 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. | | | |
