 Title    Ring-Opening of (-)-Camphorsulfonim ide Derivatives and (+)-Fenchonesulfonimide by Nitronium Tetrafluoroborate  
 Abstract    Treating a derivative o f (-)-cam phorsulfonim ide (C A name: (3aS)-8,8-dimethyl-4,5,6,7-tetrahydro-3H -3a,6-m ethano-2,l-benzisothiazole 2,2-dioxide) or the isomeric (+)-fenchone-sulfonimide with nitronium tetrafluoroborate in acetonitrile does not lead to the expected products of cationic reactions, e.g. o f the Ritter reaction for halogenated compounds, but provokes a cleavage of the sulfonim ide group with the formation of a ring-opened product containing a sulfonyl fluoride and a nitroimine group. The reaction does occur only in the presence of solid nitronium tetrafluoroborate, but not after prior dissolution of the reagent. An X-ray structure of the product from (1 S)-3-e«rfo-bromocamphorsulfonimide confirms this unusual reaction.

 Title    Eine zweite polymorphe Form von Te4(WCl6)2 A Second Polymorphie Form of Te4 (W Cl6) 2  
 Abstract    Chalkogen Polycations, Tetratellurium(2+), H exachlorotungstate(V), Synthesis, Crystal Structure The reaction of tellurium with WC16 in the presence of bromine in a sealed evacuated ampoule in the temperature range from 220 to 150 °C yields dark blue monoclinic crystals of /3-Te4(WCl6)2, space group P2!/c, lattice constants a = 664,3(2), b = 1273,2(3), c = 1233,6(3) pm, ß -94,13(3)°. The structure is built of square planar Te42+ cations and slightly distorted octahedral WC16_ anions and shows a close relationship to the previously reported triclinic a-form, which was obtained in the absence o f bromine. The difference between the two structures lies in a different packing of the ions.

 Title    Kristallstruktur und Schwingungsspektren von Zn(NH 3)4(C104)2 Crystal Structure and Vibrational Spectra of Zn(N H 3)4(C104)2  
 Abstract    The title compound Z n (N H 3)4(C104)2 crystallizes in the space group F 43m with a = 10.240(1) A. The crystal structure consists of tetrahedral Z n (N H 3)4 cations and two non­ equivalent C 104 anions with crystallographic Td symmetry. The complex ions constitute an arrangement which is known from the Zintl phase M gAgAs. The Z n(N H 3)4 cations are ccp packed with perchlorate anions in octahedral and tetrahedral voids. W hereas the C 104 ions centered at tetrahedral holes do not interact with the other lattice components, the perchlo­ rate ions in the octahedral voids are connected with the ammine ligands by a hydrogen bonded three-dimensional network involving all their N, H, and O atoms. The repeating unit of this network is a N40 4(m-H)12 cube with N -H = 1.19(2)A and O -H = 1.98(2)A . Raman and IR spectra were recorded between 150 and 4000 cm -1. A ll the expected internal m odes of the com plex ions could be detected and assigned. The crystallographically different C 104 anions have nearly the same vibrational spectra, only a slight splitting o f two IR m odes is observed.

 Title    BaCeN2, ein Bariumnitridocerat(IV) mit einer Struktur vom awf/-TiP-Typ BaCeN2, a Barium nitridocerate(IV ) with a Structure of the anti-TiP Type  
 Abstract    Reaction of Ba3N 2 with CeN in the stoichiometric ratio 1:3 at 850 °C under an atmosphere of N 2 followed by quenching yields air and moisture sensitive BaCeN 2. The product crystalli­ zes isotypically to /?-R bSc02 with the anti-TiP type structure in the hexagonal space group P 63/mmc with a = 365.06(2), c = 1266.03(3) pm, Z = 2. The structure was determined using X-ray and neutron powder diffraction data. In the structure the Ba2+ cations occupy trigonal prismatic holes with distances B a -N = 288(1) pm while the Ce atoms are in octahedral positions with distances C e -N = 242.4(8) pm.

 Title    Phasenuntersuchungen im System 2 H a -T a S 2-2 H c -M o S 2 Investigations on Phases in the System 2 H a -T a S 2-2 H c -M o S 2  
 Abstract    Ternary phases in the system TaS2-M o S 2 have been obtained by thermal reactions at 1050 °C of binary layered disulfides and N H 4C1 as promotor. Ternary phases Taj_*Mo*S2 exist in the range 0.5 < jc< 0.9. In the range of 0.25 < * < 0.55 the reactions are quantitative and the phase-compositions are determined by the amounts of the starting materials. For x < 0 .2 lT -T a S 2 and for jc> 0.60 2 H c -M o S 2 are contaminating the resulting ternary phases. Ternary phases have been characterized by X-ray powder diffraction and are indexed rhombohedrally on the basis o f a 3 R-structure with metals in trigonal-prismatic coordination. The phases Tal jcMo*S2 with 0.25 < * < 0.55 show a reversible transition of higher order asso­ ciated with a change in the electrical conductivity mechanism. B elow 420 K the phases show semiconductivity while above 460 K metallic conductivity is observed.

 Title    Alkalimetallformiate, V Die Kristallstruktur von Natriumformiat-Dihydrat, N a H C 0 2*2H20 [1] Alkali Metal Formates, V The Crystal Structure of Sodium Formate Dihydrate, N a H C 0 2-2 H 20 [1]  
 Abstract    Single crystals of sodium formate dihydrate, N a H C 0 2-2 H 20 , have been prepared from aqueous solutions of sodium formate, N a H C 0 2, via the trihydrate, N aH C O 2-3 H 2O .0They are orthorhombic, space group Cmca, with a = 7.070(4), b = 14.534(2), c = 8.706(2) Ä and Z = 8. The structure, including the hydrogen atoms, was refined to R = 0.054, Rw = 0.065 for 479 unique reflections with I > 3 a (I). It comprises buckled layers formed by N aO fi octahedra which are edge-and corner-sharing. The octahedral coordination of the sodium ions is achie­ ved by two oxygen atoms from two different end-on bonded formate ions and four water oxygen atoms. The O —H distances show clearly that strong hydrogen bonds are not involved in the bonding system.

Synthesis, Structure, Electrochemistry and ESR-Spectra Tripod Ligands, 1,2-Benzenedithiolato, Five-fold Coordination of Fe(III), Co(III) and Co(II), X-Ray, ESR Spectra The d6-C o(III)-species [tripodCo-(ortho-(X.)(Y)C6H4)]+ (X, Y = O, S, tripod = CH3C (C H 2PPh2)3) 1 are reversibly reduced to the neutral d7-Co(II)-com pounds [tripodCo-(ortho-(X)(Y)C6H4)] (X, Y = O, S) 2. Both species show fivefold coordination of cobalt with coordination polyhedra in between the limits of the square pyramid and the trigonal bipyramid respectively. The low-spin d7-species 2 give clearly resolved ESR-spectra revealing the coexistence of two geometric isomers above -8 0 °C, with only one isomer persistent at temperatures around 100 K. A s an analogous d5-system [benzyltripodFe-(ortho-(S)(S)C()H4)]+ 3 (benzyltripod = C6H 5CH2C (CH 2PPh2)3) has been obtained from [öe«z_y/rr//70ö?Fe(NCCH3)3]2+ and C6H 6S2. Alternatively complexes o f this type, e.g. [m poJFe-(orf/io-(S)(S)C 6H 4)]+ 4, may be prepared from F e(H 2Ö)6(BF4)2/rnpod/C6H6S2 when the reaction mixture is activated by acidification with H B F4. The geometry of the ds-species 3 and 4 is close to a trigonal bipyramid.

Two identical [FeL(M eOH)Cl] fragments, related by an inversion centre, are combined by the two bridging O atoms, to form a binuclear unit. The iron(III) centers are separated by 3.163(2) A and weakly antiferro-magnetically coupled (J = -8 .0 (1) cm -1), which follows from temperature -dependent mag­ netic susceptibility m easurements in the range 4.2 to 288 K. The effective magnetic moment per iron(III) is /ueff = 7.4 /uB at 288 K.

 Title    Neue mono-und spirobicyclische Aminosilane: Synthese, Struktur und Eigenschaften New M ono-and Spirobicyclic A m inosilanes: Synthesis, Structure and Properties  
 Abstract    The reactions of the N.N'-dialkyl/aryl-ethylenediamines l a -e with equimolar amounts of tetrachlorosilane give the monocyclic aminosilanes 2 a -e in good yields. With two equivalents of the diamines 1 only one spirobicyclic compound, l,4,6,9-tetrabenzyl-l,4,6,9-tetraaza-5-sila-spiro[4.4]nonane, 4e, can be prepared. It is only via an independent double deprotonation of the diamines that the spirobicyclic ethyl-and isopropyl derivatives 4a and 4b are also becoming available. A ll compounds have been characterized by multi-NMR and mass spec­ trometry. In three cases (2d, 2e and 4e), the crystal and molecular structures have been determined by X-ray diffraction analysis. A planar silaimidazolidine ring system has been confirmed for the phenyl substituted species 2d, while in the corresponding benzyl substituted hom ologue 2 e both nitrogen atoms are pyramidal and lead to ring puckering. The silicon atom in 4 e shows a strongly distorted tetrahedral coordination. The endocyclic angle N l -S i -N 2 = 92.8(1)° is nearly orthogonal, and the angle between the planes defined by the silicon and the two nitrogen atoms o f the five-membered rings is 81.4(1)°.

 Title    Crystal Growth and X-Ray Structure of Metastable «-KC0 PO 4  
 Abstract    Crystals o f KC0PO4 were obtained by growth in a gel of tetramethoxysilane/water at 64 °C. The hexagonal crystals have space group P 63, a = 18.206(1), c = 8.5135(8) [Ä], V = 2443.8(4) [A 3]. Z = 24. The structure was solved by single crystal X-ray diffraction methods. The struc­ ture is isotypic with a -K Z n P 0 4. It comprises an ordered three dim ensional network o f alter­ nating C oÖ 4 and P 0 4 tetrahedra. which has rings of six tetrahedra in the xy plane. These rings form tunnels in the [001] direction, where the potassium ions are located. U pon heating, the compound undergoes a phase transition at about 565 °C; on cooling, the phase transition occurs at 449 °C, where it transforms into another structure which is yet unknown. This indicates that the hexagonal structure is a metastable phase.
