 Title    Röntgenographische Strukturuntersuchung von Cäsiumhexaoxo-tetrahydroxo-pentaborat-2-dimethylsulfoxid X-ray Study of the Structure of Cesiumhexaoxo-tetrahydroxo-pentaborate-2-dimethyl Sulfoxide  
 Abstract    The compound Cs[Bs0 6 (OH)4 ] • 2 DMSO was prepared by hydrolysis of tris(methoxy)-borane in organic solvents with small amounts of water in presence of cesium ierf-butylate and recrystallized in DMSO (dimethyl sulfoxide). Cs[Bs0 6 (0 H)4 ] • 2 DMSO crystallizes in the monoclinic space group P2i/a with a = 9.593(2), 6 = 19.179(4), c = 11.585(2) Ä, ß = 119.99(2)° and Z — 4. The crystal structure was determined by single-crystal diffracto­ meter data and refined to a conventional R value of 9.9%. The crystal structure consists of chains of pentaborate anions [Bs0 6 (OH)4 ]-linked by hydrogen bonds. The cesium cation and the DMSO molecules join the chains to sheets by coordination and hydrogen bonds respectively.

 Title      
 Abstract    G e r h a r d C o r d i e r u n d H e r b e r t S c h ä f e r BaMnSb2, SrMnBi2 and BaMnBi2 have been prepared and structurally characterized. The new compounds are isotypic and crystallize tetragonal in the SrZnBi2 structure with the following constants: BaMnSb2: a = 4.53 ± 0.01 A, c = 24.34 ± 0.03 A, c/a = 5.37. SrMnBi2: a = 4.58 ± 0.01 A , c = 23.13 ± 0.03 A, c/a = 5.05. BaMnBi2: a — 4.63 ± 0.02 A, c = 24.22 i 0.05 A, c/a = 5.23. The transition metal atoms form together with the semimetal atoms sheets of tetragonal pyramids separated by double layers of alkali earth atoms. In these double layers there are inserted Bi/Sb-square nets.

 Title    Ein Beitrag zur Kristallchemie dreiwertiger Seltenerdoxide Zur Stabilisierung der m onoklinen B-Form  
 Abstract    Single crystals of 1 — a'Ho203 : xCaO (x = 0.07), CaHoC>2.5 (A) and Cao.5H 01.5O2.75 (B) were prepared by high temperature reaction and investigated with X-ray single crystal data. It can be shown that small amounts of CaO stabilize the monoclinic B-Typ of rare earth oxides. Phase (A) and (B) cannot be seen as a stabilized B-type crystal because they have an new crystal structure with space group C.7h-P 2 i/m, a = 656.6, b = 356.7, c = 529.4pm , ß = 92.3°; a = 650.2, b = 352.4, c = 584.5, ß = 92.3°.

 Title    Über die Tricyanatomercurate KHg(NCO)3 und RbHg(NCO)3 - Synthesen, Kristallstrukturen und Schwingungsspektren  
 Abstract    On th e Cyanatom ercurates K H g(N C O)3 and R bH g(N C O)3 -Syntheses, Crystal Structures and V ibrational Spectra G e r h a r d T h i e l e u n d P e t e r H i l f r i c h B y m ixing aqueous solutions of Hg(CH3COO)2 and KOCN the white precipitate K 2 Hg3(NCO)8 is formed. When recrystallised from CH3OH colorless crystals of the compound KHg(NCO)3 are obtained. The crystal structure analysis (space group Pnma; a — 1015.2(6) pm, b = 399.3(3) pm, c = 1772.9(9) pm) shows a distorted KCdCl3 arrange­ ment w ith isolated Hg(NCO)2 molecules, K+ and NCO~ ions. The vibrational spectra in the range of 250-3000 cm-1 are discussed. The rubidium compound is isotypous (a = 1019.0(6) pm, b = 411.6(4) pm, c = 1820.5(8) pm).
