 Title    Zur Polymorphie des Cadmiumsulfits, Kristallstrukturen von CdS0 3 -I, CdS0 3 -II und CdS0 3 -III Polymorphic Cadmium Sulfites, Crystal Structures of CdS0 3 -I, CdS0 3 -II, and CdSO r III  
 Abstract    The crystal structures of the anhydrous cadmium sulfites CdS0 3 -I (¥2 x /c, Z=4), CdS0 3 -II (P2/C, Z=8), and CdS0 3 -III (R3, Z=18 for the hexagonal cell) have been determined by means of single crystal X-ray diffraction data. The final R for the 1475, 2349, and 2138 observed reflections are 0.040, 0.034, and 0.073. Coordination of Cd is trigonal-prismatic, a hitherto unknown coordination of Cd in salts of oxoacids, in CdS0 3 -I and CdS0 3 -II, and octahedral in CdS0 3 -III. The Cd0 6 -polyhedra are arranged in two-dimensional (CdS0 3 -I) and three-dimensional (CdS0 3 -II and CdS0 3 -III) networks. S0 3 2-groups act as monodentate and in CdS0 3 -I and CdS0 3 -II also as bidentate ligands. Cd—O distances range from 224.5(3) to 244.6(3) pm, with an average of 231.5 pm for the trigonal-prismatic and of 231.0 pm for the octahedral coordination. S—O dis-tances range from 152.3(3) to 155.3(3) pm with an average of 153.7 pm, the O —S—O angles from 99.2(2) to 106.7(3)° with an average of 103.2°.

 Title    Tritelluride mit komplexierten Kationen: Darstellung und Kristallstruktur von [Ba(en) 3 ]Te 3 und [Ba(en) 4;5 ]Te 3 Tritellurides of Complex Cations: Synthesis and Crystal Structure of [Ba(en) 3 ]Te 3 and [Ba(en) 4 5 ]Te 3  
 Abstract    The two title compounds have been prepared by reaction of appropriate mixtures of the elements in ethylenediamine. The structures have been determined on the basis of single crystal data. [Ba(en) 3 ]Te 3 crystallizes in the monoclinic system, space group P2 (/c with a = 918.0(4), b — 1203.7(6), c = 1639.9(6) pm, ß = 93.4(1)°. In the structure there are bent tritelluride anions Te 3 2 ~ (bond lengths 273.9—278.5 pm, bond angle 105.7°). The Ba 2+ cations are six coordinate by the bidentate ligand ethylenediamine. [Ba(en) 4 5 ]Te 3 crystallizes in the monoclinic system, space group Cc with a = 1752.8(6), b = 938.9(4), c = 3041.7(8) pm, ß = 91.3(1)°. In this structure the bond lengths in the Te 3 2 ~ anions are shorter (272.1—273.1 pm, bond angles 110.9—112.2°). The cations are coordinated by four bidentate ligands, and are connected into pairs by a further ethylenediamine molecule. The resulting dinuclear [Ba(en) 4 ]en[Ba(en) 4 ] 4+ units have the Ba 2+ cations in CN 9.

 Title    Darstellung und Kristallstrukturen von (Ph4P)4Sb8I28 und (Ph4P)Sb3l 10 (Ph = C6H5) Synthesis and Crystal Structures of (Ph4P)4Sb8I28 and (Ph4P)Sb3 l 1 0 (Ph = C6H 5)  
 Abstract    The compounds (Ph4P)4Sb8l 28 (1) and (Ph4P)Sb,Iio (2) were prepared by the reaction of Sbl3 and Ph4PI in acetonitrile (molar ratios 2:1 and 3:1 respectively). The structures of 1 and 2 were determined from single crystal X-ray diffraction data. 1 crystallizes in the triclinic space group P I with a = 1321.7(5), b = 1346.7(5), c = 2201.8(8) pm, a = 104.18(2), ß = 99.92(2), y = 100.33(2)°; 2: monoclinic, C2/c, a = 2371.1(2), b = 745.0(1), c = 2495.1(2) pm, ß = 100.75(1)°. Whereas 1 exhibits isolated SbsI284' ions, the anions of 2 are built up of polymeric chains [Sb3I 10_]x. In both compounds the distorted Sbl6 octahedra are linked by common edges. The Sb—I distances are in the range between 277.4 and 354.8 pm (1) and between 277.4 and 342.4 pm (2). The observed structures do not only depend on stoichiometry. the nature of the counter cations, and the possibility of oligomerisation but also on the wide variety of the Sb—I bond strengths and the different bridges formed by iodine. The lone pair of Sb(III) seems to be predominantly 5s: .

 Title    EPR-Spektren von Tetrachlorocupraten verschiedener Aminothiazoliumderivate. Die Kristallstrukturen von 2-Amino-2-thiazolinium-und 2-Amino-4-methylthiazoliumtetrachlorocuprat(II) EPR Spectra of Tetrachlorocuprates of Several Aminothiazolium Derivatives. The Crystal Structures of 2-Amino-2-thiazolinium and 2-Amino-4-methylthiazolium Tetrachlorocuprate(II)  
 Abstract    The tetrachlorocuprates. of the 2-aminothiazolium ion and of four of its substitution products, of 2-aminothiazolinium, and of 2-amino-4-carboxyl-thiazolidinium ions were prepared from the cor-responding heterocyclic bases, hydrochloric acid and copper(II) chloride in ethanol. The thermo-chromic compounds were characterized by their IR and electronic spectra. The EPR spectra of solutions, frozen solutions, and of the solids show the CUC14 2 ~ ion to have the structure of a flattened tetrahedron; in the case of some of the solids, distortions from D 2 d symmetry are observed. This was confirmed by two X-ray crystal structure determinations. Crystal data: 2-amino-2-thiazolinium tetrachlorocuprate, monoclinic, space group C2/c, a = 2772.8, b = 780.0, c = 1560.0 pm, ß = 112.04°, Z = 8 (R = 0.047 for 2527 observed, independent reflexions); 2-amino-4-methylthiazolium tetrachlorocuprate, triclinic. PI, a = 780.4, b = 853.4, c — 1381.4 pm, a = 103.50, ß = 99.39, y = 104.17°, Z = 2 (R = 0.041 for 3319 reflexions). In both compounds the flattened CuCl 4 2 " tetrahedron is distorted and has two bond angles in the range between 130 and 141°. The heterocyclic cations are protonated at their ring N atoms; the corresponding H atoms and the H atoms of the amino groups are involved in N — H--C1 hydrogen bonding.

 Title    Cyclodi-und -trisilazane — Synthese, Reaktionen und Ringkopplungen Cyclodi-and -trisilazanes — Synthesis, Reactions and Ring Coupling  
 Abstract    Contrary to our expectations, a cyclotrisilazane is obtained instead of a cyclodisilazane by the reaction of the lithiated di-rerf-butyldiamino-silane with Hal 2 SiMe 2 . Mono-and disubstitution takes place in reactions of lithiated tetra-isopropyl cyclodisilazane with halogeno-silanes and -boranes. A disubstituted ring reacts with LiOC 4 H 9 -formed from LiC 4 H y and THF — to give an unsymmetrically substituted four-membered ring as proved by a crystal structure determination. Coupling of four-and six-membered rings occurs in the reaction of SiF-substituted and lithiated rings.

 Title    Darstellung und Kristallstruktur von NaCu 3 Te 2 Preparation and Crystal Structure of NaCu 3 Te 2  
 Abstract    The title compound was prepared by reacting a corresponding mixture of Na 2 Te 2 , copper and tellurium at 700 °C. NaCu 3 Te 2 forms crystals of metallic lustre which are rapidly decomposed in humid atmosphere. It crystallizes with a rhombohedral structure, space group R3m, with a — 4.276(3) Ä, c = 23.78(1) Ä. Z = 3. The crystal structure was determined from diffractometer data and refined to a conventional R of 0.050 for 135 independent reflections. The atomic arrangement of NaCu 3 Te 2 is based on a c.c.p. array of tellurium atoms with stacking sequence c 6 . Na and Cu occupy alternatingly the interstitial layers. Na is in an octahedral coordi-nation (d Na _ Te : 3.22 A), the Cu atoms occupy the tetrahedral and the octahedral voids. They are, however, shifted from the centers of these sites, resulting in an 1 + 3 coordination (d Cu _ Te : 2.70 Ä) for Cu on the tetrahedral. and an essentially trigonal coordination (d Cu Xe : 2.575 A) for Cu on the octahedral sites. NaCu 3 Te 2 shows no closer structural relationships to the other alkali-copper-chalcogenides known so far. However, its crystal structure may be interpreted as an ordered defect derivative structure of the CaCu 4 P 2 -type [1].

 Title    Synthese und absolute Konfiguration kettenverzweigter, Cimetidin-analoger Thioether Synthesis and Absolute Configuration of Chain Branched Cimetidine Analogous Thioethers  
 Abstract    Chain branched Cimetidine analogous thioethers. promising building blocks for the preparation of H : -histaminergic compounds, were svnthetized from chiral aminoalkanethiols. Enantiomeri-callv pure amino acids or aminoalcohols were used as starting materials. In one case, a resolution via neutral and acid di-0-(4-toluoyl)tartrates was achieved in good yields and satisfying enan-tiomeric excess. The absolute configuration of an ethyl branched compound was determined using X-ray diffraction and anomalous dispersion.

 Title    Hydroxy Complexes of Gold 2. Calcium Aurates [1]  
 Abstract    Two calcium aurate phases have been obtained as single crystals, phase 1 from H AUC1 4 + Ca(OH) 2 and phase 2 from NaAu(OH) 4 + Ca(C10 4) 2 . An X-ray structure determination of 1 shows its composition to be Ca 2 (0H) 3 (H 2 0) 4 [Au(0H) 4 ]. The apparent space group is Cmcm, but this corresponds to a sub-cell of the true structure. The disordered Cmcm structure was refined to R 0.032 for 813 reflections. The coordination geometry is square planar at gold (Au-O 1.97, 1.99 Ä), cubic at Ca(l) and octahedral at Ca(2). Phase 2 crystallizes in a primitive tetragonal cell with a 6.94, c 7.71 Ä; it is probably Ca[Au(OH) 4 ] 2 , but this has not yet been confirmed by a full structure determination.

 Abstract    The compounds Ga 2 Br 4 (a+ß) have been prepared by reacting GaBr 3 with Ga metal without a solvent or in a hydrocarbon medium. a-Ga 2 Br 4 is isotypic with Ga 2 Cl 4 , and /3-Ga 2 Br 4 with Ga 2 I 4 . Both forms have to be formulated as Ga + (GaBr 4)~ according to their crystal structures. The first order phase transition a—*ß has been investigated by means of DTA and temperature dependent X-ray powder photographs. The crystal structure of /3-Ga 2 Br 4 has been refined with single crystal data (R3c; a = 2163.4(8) pm; c = 869.2(4) pm; Z = 18; R = 0.037). Main building units are GaBr 4 " tetrahedra (d(Ga —Br) = 232.9 pm), connected in three dimensions by capped trigonal prisms (6+2+1) around Ga + . The crystal chemical relationships between y3-Ga 2 Br 4 and Ga 2 I 4 are discussed.

 Title    das erste Chalcogenid mit zweiwertigem Aluminium Al 7 Te 10 — the First Chalcogenide of Divalent Aluminum  
 Abstract    Al 7 Te 10 is prepared from a melt of the elements in stoichiometric amounts in a corundum crucible contained in a sealed quartz ampoule. The ruby red cube shaped crystals are stable below 840 K. The structure of Al 7 Te, 0 (R32-D^; a = 1439.5 pm, c = 1793.2 pm, Z = 6, R = 0.03) is a distorted defect variant of a tetrahedral arrangement of the 4H-polytype. The central unit, a double barrelane [Te 4 Al 4 —Al 4 Te 4 ], contains an Al —Al bond of 260 pm, which is somewhat longer (n = 0.83) than an expected single bond (250 pm, n = 1). This homopolar bond disturbs the electrostatically favorable (Al—Te—)" sequence in the structure which is compensated by the occurrence of four-membered Al 2 Te 2 rings. Al 7 Te 10 is a Zintl phase according to l/2{[Al 2+ -Al 2+ ][Al 3+ ] !2 [Te 2 ~] 20 } and exhibits semiconducting and diamagnetic behaviour.

 Title    Synthesis and Crystal Structure of PbZn(NCS) 4  
 Abstract    PbZn(NCS) 4 is obtained from the binary compounds Pb(SCN) 2 and Zn(NCS) 2 with traces of water in an ultra-sound bath. The space group of the complex is Pn2[a (standard: Pna2,) with Z = 4. The structure consists of as-connected octahedra ^.[PbS 2 S 4/2 ] forming two-dimensional layers. All SCN-groups are bound to Zn 2+ via their N atoms. The resulting ZnN 4 tetrahedra are arranged in the cavities formed by the PbS 6 octahedra.

 Abstract    IR, Raman and NMR spectroscopic studies of dimethyl(methylthio)-and dimethyl(phenyl-thio)sulfonium salts (CH 3) 2 SSR + A~ (R -CH 3 , C 6 H 5 ; A = AsF 6 ~, SbCl 6 ~) are reported. The crystal structure of (CH 3) 2 SSCH 3 + AsF 6 ~ shows for the cation a conformation different from that reported for the hexachloroantimonate.

 Title    Darstellung und Kristallstrukturen von C a^ ^ N und Sr4In2N  
 Abstract    The new compounds Ca4In2N and Sr4In2N crystallize in the tetragonal system (space group 14,/am d, No. 141). In and Ca together form a rocksalt structure. All octahedral holes, which are built by Ca only, are occupied by nitrogen. The In atom s form In —In zig-zag-chains; the In —In bond lengths are 316.4 pm (Ca com pound) and 332.0
