 Title    Oxotitanate mit gemischter Valenz, II Zur Kenntnis von Sr2Ti6013 Oxotitanates with Mixed Valence, II About Sr2Ti60i3  
 Abstract    Single crystals of Sr2TieOi3 were prepared by heating a mixture of SrO • Ti203 • 2 TiOo in a vacuum furnace to 1800 °C for 6 hours. X-ray investigations show monoclinic sym-metry (a = 1525,0, b = 376,9, c = 916,4 pm; ß = 99,15°, space group Cgh-C2/m). Sr2Ti60i3 is isotypic with Ba2Ti60i3.

 Title    Zur Darstellung und Struktur von CaMnBi 2 On the Preparation and Crystal Structure of CaMnBi2  
 Abstract    The new compound CaMnBi2 has been analytically and structurally characterized. CaMnBi2 crystallizes in the tetragonal system (a — 450 ^ 1 pm, c = 1108 ± 2 pm, space group P4/nmm). Mn and Bi atoms form fourfold pyramids, connected by common edges in the basis to two-dimensional sheets. These sheets are separated by double layers of Ca atoms between which further Bi atoms are located forming squarenets. The structure is strongly related to that of SrZnSb2 which can be interpreted as a distorted variant of the new CaMnBi 2 type.

 Title    Cyclische Diazastannylene, VIII [1] Die Kristall-und Molekülstruktur eines Iminostannylens: Sn3 (NC(CH3 )3 )4 H2 Cyclic Diazastannylenes, VIII [1] The Crystal and Molecular Structure of an Iminostannylene: Sn3(NC(CH3)3)4H2  
 Abstract    The crystal and molecular structure of the compound Sn3(NC(CH3)3)4H2 has been determined from X-ray data (R = 0.044). The crystals are cubic, space group Pa3, with cell dimension a — 1713.6(8) pm and Z = 8. The molecules, which have a seco-norcubane like Sn3N4 framework, are statistically disordered, thus forming closed packed pairs of molecules. The Sn3N4 cage deviates strongly from a cube, the bond angles at Sn approach-ing 80°, and at N 100°. The averaged Sn-N bond distance is 223(1) pm.

 Title    Die Kristallstruktur des Xl10Hg3Cl16 The Crystal Structure of Tli0Hg3Cli6  
 Abstract    The structure of TlioHggClie (tetragonal; space group I4/m; a — 849,0(2) pm, c = 2372,9(6) pm) was determined by X-ray structure analysis. This compound consists of HgCLi tetrahedra and linear Cl-Hg-Cl units, which are completed by four additional chlorides to distorted (2 + 4) HgCle octahedra. A close relationship to the Tl4HgXe structure (X = Br, I) is discussed.

 Title    Die Kristall-und Molekülstruktur zweier spirocyclischer Diazadiphosphetidine The Crystal and Molecular Structure of Two Spirocyclic Diazadiphosphetidines  
 Abstract    The crystal structure of the two spirocyclic diazadiphosphetidines (Me2C202)(Me2N)2P2N2(SiMe3)2 (1) and (Me2C202)2(Me2N)2P2N2(SiMe3)2 (2) were deter-mined. In both compounds the dimethylamino groups are arranged in a eis position with respect to the plane of the four-membered ring. There are no unusually long PN distances in the four-membered ring of 2, although 2 monomerizes easily and quantitatively at room temperature to give 3.

 Abstract    N-Organylamino-N',N'-bis(trimethyl)amino-fluoroorganylsilanes react with butyl-lithium to give the corresponding lithium salts. Further reaction of these lithium salts with fluorosilanes leads to the formation of the expected substituted compounds. Diaza-disilacyclobutanes are formed by thermal LiF elimination in THF. The simultaneous 1,3-migration of a trimethylsilyl group from one nitrogen atom to another is demonstrated by the crystal structure determination of the products of two such reactions, with different substituent groups.

 Abstract    The crystal structure of (H30)[Al3(H2P04)6(HP04)2] • 4 H20 contains layers consisting of AIOÖ octahedra which share vertices with 02P(0H)2 and 03P(0H) tetra-hedra. Within these layers there are vacancies (hollows) which are occupied by H30+ species. Water molecules are fixed between neigh-bouring layers by hydrogen bonds. The identity of some other related phosphates is discussed with respect to the crystal structure described in this paper.

 Abstract    Semicobaltates (Co-1/2) containing olefin and trimethylphosphane ligands are synthe-sized from Co(olefin)(PMe3)3 and potassium metal. The X-ray crystal structure determina-tion of the title compound shows that the unit cell contains two K atoms in equal ionic contact with the ethylene ligands of four Co(C2H4)(PMe3)3 complex units, two of which are interacting with both K atoms. In solution the semicobaltates exist in hydrocarbon solvents under argon only, while in contrast under ethylene or nitrogen atmospheres or in donor solvents disproportionation occurs to give Co(O) and Co(-I) species.

 Abstract    The new compounds TböBr? and Er6l7 are formed from the trihalides with an excess of metal in sealed tantalum containers. X-ray structure investigations [space group C2/m; Tb6Br7 (Er6I7): a = 2057.1 (2137.5), b = 379.3 (386.9), c = 1180.0 (1231.9) pm, ß = 124.59° (123.50°)] show one-dimensional regions connected by Ln-Ln bonds. The structure type can be described in terms of LnöXi2-clusters which are linked via edges of Ln6-octahedra to form double strings. The structure is derived from an FCC arrangement of halogen atoms part of which is systematically substituted by Ln6-octahedra.

 Abstract    W. Zeiß et al. • (MePNMe)4S3, ein Cyclotetra(A 3 ,A 5 ,A 5 ,A 5 -phosphazan) (MePNMe)4S3, a Cyclotetra(A 3 ,A 5 ,A 5 ,A 5 -phosphazane) 31 P} Decoupling Octamethylcyclotetra(A 3 -phosphazane) (1) reacts with three mole equivalents of sulfur, added either in excess or in deficite, to give 2, the first cyclotetra(A 3 ,A 5 ,A 5 ,A 5 -phosphazane). Its crystal structure determination shows a completely unsymmetrical molecule, which does not undergo ring inversion in solution. Thus an ABMX spin system with remarkably different AM and BM coupling constants is observed in the 31 P{ 1 H} NMR spectrum. By means of selective { 31 P} decoupling, all CH3 proton signals could be assigned in the 1 H NMR spectrum.
