The compound has been separated by extraction with dichloromethane in the presence of tetrabutylammoniumbromid and precipitated from the organic phase by adding CsCH3COO/C2H5OH. The Crystal structure of Cs[B6H6(NH2)] H20 has been determined by single crystal X-ray diffraction analysis; monoclinic space group C2 with a = 22.1075(14), b = 6.491(2), c = 5.9570(4) Ä, ß = 100.168(6)°. The UB NMR spectrum is consistent with a mono-hetero-substituted octahedral B6 cage with local C4v symmetry. The IR and Raman spectra exhibit characteristic N -H , B -H and B6 vibrations.

 Abstract    In the crystal structure of K34[Zn2()In85] (a = 1827.7(5) pm, c = 3980.5(8) pm, R3m , Nr. 166, Z = 3, R1 = 0.056, wR2 = 0.124) the In and Zn atoms form the /3-rhombohedral boron structure. The structure contains In84 Samson polyhedra, and clusters of 18 In and 10 Zn atoms, forming three In12 icosahedra sharing two common triangular faces. The potassium atoms occupy the centres of truncated tetrahedra -forming the Samson polyhedra -and Kasper polyhedra.

 Title    Kristallstrukturuntersuchung an einem Strontium-Vanadyl-Vanadat: Sr2(V 0 )V 20 8 Crystal Structure Investigation of the Strontium Vanadyl-Vanadate: Sr2( V 0 ) V 20 8  
 Abstract    Single crystals of Sr2(V 0)V 20 8 have been prepared by quenching melts from higher tem­ peratures. This compound represents a new structure type and crystallizes with monoclinic symmetry, space group C |h-I 2 la, a = 6.929, b = 16.246, c = 7.260 A, ß = 115.82°, Z = 4. The point positions occupied by V5+ show tetrahedral coordination. The refinement of the V4+ position led to split positions with acentric orientations of V4+ in the octahedral O2-surrounding. It results in a square pyramidal coordination with one short V -O distance typically for vanadyl groups.

 Title    Preparation and Crystal Structure Determination of [(C2H5 )4 N]2Hg3 Cl8  
 Abstract    X-Ray, Tetraethylammonium Chloromercurate, Cluster of [Hg3Cl8]2_ The title compound has been prepared in two different ways: First, by boiling single crystals of [(C2H 5)4N]H gC l3 in a mixture o f n-hexane/n-octane [4:1] at T = 350 K, and second, in a synthesis from stoichiometric quantities of the components. X-ray structure analysis gave the stoichiometry [(C2H 5)4N]?Hg3Cl8, monoclinic, space group P 2 1? a = 7.538(3), b = 19.909(6), c = 10.274(3) A , ß = 95.13(1)°, V = 1535.7(9) A 3, Z = 2. The basic [Hg3Cl8]2--units form broken zig-zag chains along [100]. The H g -C l distances within the [Hg3Cl8]2~ clusters range from 2.315(3) to 2.755(4) A. This is a new coordination type for halomercurates.

 Abstract    [C aN R -CPh=CPh-N R (D M E)2] 1 (R = C6H4-4 -C H 3; D M E = dim ethoxyethane) was pre­ pared by reaction of calcium with N R = C P h -C P h = N R in D M E solution. The compound forms orange, moisture sensitive crystals, which were characterized by an X-ray structure determination [space group orthorhombic, P 2 i2 12 1, Z = 4, 4634 observed unique reflections, R = 0.046; lattice dimensions at -7 0 °C: a = 1340.2(3), b = 1528.1(3), c = 1609.1(3) pm]. The calcium atom is coordinated by the four oxygen atoms of two chelating D M E molecules and two nitrogen atoms of the diazadiene ligand, bonded in its enediam ide form. [Ba2(D M E)3(N P h -C P h = C P h -N P h)2 DM E] 3 was obtained from barium metal and N Ph=C Ph-C Ph=N Ph in D M E solution as red crystals [space group monoclinic, P2!/c, Z = 4, 4000 observed unique reflections, R = 0.166; lattice dim ensions at -7 0 °C: a = 1704.5(3), b = 1786.1(4), c = 2177.4(4) pm, ß = 105.98(3)°]. The two barium atoms are bridged by two differently bonded diazadiene ligands (/<2-N ,N ';/i-N ,a -N '). Additionally, one of the barium atoms is coordinated to two DM E m olecules and the other one to only one of the ether molecules. A further DM E molecule is a constituent of the crystal lattice.

 Abstract    Di-terf-butyldifluorosilane reacts with N-lithium -N',N'-dimethylhydrazine in a molar ratio 1:1 to yield the N-di-ferf-butylfluorosilyl-N',N'-dimethylhydrazine 1. The lithium derivative of 1 (2) forms a dimer with the nitrogen atoms coordinated "side-on" to the lithium atoms. The silylation with M e3SiCl gives product 3. Heating 2 in a vacuum leads to the cyclo-disilazane derivative 4. A bis(hydrazino)fluoroborane (5) is obtained in the reaction of 2 with trifluoroborane-etherate.

 Abstract    The title compound, formed by the reaction o f acetophenone with 3-diethylamino-1-propylamine and sulfur, crystallizes in the orthorhombic space group P 2 12 12 1 (Z = 4) with lattice constants a = 818.1(2) pm, b -1225.1(2) pm and c = 1622.4(4) pm. The characterization of the molecule as a zwitterion is established by the observed bond parameters. Both spec­ troscopic investigations and the results of the X-ray structure determination show that a hydrogen atom is bonded to the amino nitrogen rather than to the imino nitrogen.

 Title    Tautomere Wasserschichten. Bildung und Struktur tiefschmelzender Trihydrate von Triethylamin und 4-Methylpyridin [1] Tautomeric Water Layers. Formation and Structure of Low-Melting Trihydrates of Triethylamine and 4-Methylpyridine [1]  
 Abstract    Low-melting trihydrates of triethylamine (E t3N) and 4-methylpyridine (4-M ePy) have been confirmed and detected by phase analysis and the crystal structures determined. Both are monoclinic with space group P 2!/c and Z = 4 formula units per unit cell. The lattice parameters are a = 13.606, b = 6.291, c = 12.412 A , and ß = 99.47° at -1 0 0 °C for Et3N -3 H 20 , and a = 9.982, b = 6.877, c = 12.958 Ä , and ß = 103.50° at -9 0 °C for 4-M eP y-3 H20 . The water m olecules in the two structures are hydrogen-bonded in condensed four-, five-, and six-membered rings with 1:2:1 ratio, thus forming characteristic layers parallel (1 0 0) of identical topology and tautomeric to each other. The amine m olecules are linked to both sides of the layers by O -H — N bonds from different O atoms.

 Title    Tetrakis(tetrahydrofuran-0)calcium-und -strontium-bis[bis(trimethylsilyl)- arsanid] -Vergleich der spektroskopischen Parameter sowie der Molekülstrukturen Tetrakis(tetrahydrofuran-0)calcium and Strontium Bis[bis(trimethylsilyl)- arsanide] -A Comparison of the Spectroscopic Param eters and the Molecular Structures  
 Abstract    Calcium-and strontium bis[bis(trimethylsilyl)amide] react with bis(trimethylsilyl)arsane in tetrahydrofuran to give the corresponding tetrakis(tetrahydrofuran-O) metal bis[bis(trime-thylsilyl)arsanides]. The calcium derivative crystallizes in the triclinic space group P I with a = 1191.7(2), b = 1232.0(2), c = 1655.0(2) pm, a = 102.46(1)°, ß = 107.92(1)°, y = 104.66(1)° and Z = 2, the strontium derivative in the orthorhombic space group Pbca with a = 2153.4(3), b = 1852.2(3), c -2182.4(3) pm and Z = 8. Both m olecules exist as frans-isomers with a nearly linear A s -M -A s moiety; however, the strontium analogue contains two remarkably different configurations for the arsenic atoms. One A s atom is surrounded nearly trigonally planar with a S r -A s bond length of 310 pm, whereas the other pnictogen atom has an angle sum of 338° with a S r -A s distance of 315 pm.
