	Title	Kristallstruktur der stabilen Modifikation von SeQi Crystal Structure of the Stable Modification of SeCU
	Abstract	Single crystals of the stable modification of selenium tetrachloride (a-SeCU) were grown by sublimation, and the crystal structure was determined. As that of metastable ß-SeCU it contains tetrameric cubane-like molecules Se4Cli6, but with different point symmetry and in positions which correspond to those of the atoms of the tungsten structure type.

	Title	Die Struktur des Na7Ga13-I und ein Konzept zur bindungsmäßigen Deutung The Structure of NavGai3-I and its Characterization by a Bonding Scheme
	Abstract	The new compound NayGa^-I crystallizes in the trigonal-rhombohedral system, space group R 3 m, with the constants a = 1496.5(3) pm, c = 3893(1) pm, c/o = 2.60. The Ga atoms form Gai2 icosahedra and Gais clusters, connected to a threedimensional net. The arrangement of these clusters is related to the MgCu2 structure. The Na content of this compound correlates with the number of electrons necessary for a stable electron configuration in the Ga partial structure. The BaAl4 type structure of NaGa4 has been confirmed by single crystal data.

	Title	Phasenbeziehungen im System As2Te3—Asl3 und die Kristallstruktur von As5Te7I Phase Relations in the System As2Te3-Asl3 and the Crystal Structure of AssTe7l
	Abstract	The system As2Te3-Asl3 is quasibinary and includes the intermediate phases AssTe7l and a-AsTel with incongruent melting behaviour. The crystal structure of AssTe7l contains ribbons of condensed octahedral chains sharing common edges. Arsenic atoms are situated in the centres of the octahedra and -in a trigonal-pyramidal arrangement -at the borders of the ribbons. There are close relationships between the crystal structures of As2Te3 and AssTe7l as well as As5Te7I and a-AsTel. The particular expansion of the AsöTe7l one-phase region within the quasibinary system is discussed with respect to these structural relations.

	Title	Cyclisierungsreaktionen lithiierter Fluorsilanole und Aminofluorsiloxane - Kreuzdimerisierung eines Silicenium-Ylids Cyclisation Reactions of Lithiated Fluorosilanols and Aminofluorosiloxanes - Cross-dimerisation of a Silicenium-Ylid
	Abstract	KOH reacts with bis(isopropyl-trimethylsilyl)-amino-difluorosilane to give the fluoro-silanol 1. An aminofluorosiloxane 2 is obtained in the reaction of [(Me3Si)2N]2SiF2 with KOH via a 1,3-silyl-group migration. The four-membered SiOSiN ring 5 can be prepared in several steps from 1. Six-membered SiO rings 8-10 are formed in the reaction of 1,3-fluorosilanols 6 and 7 with butyllithium. Lithiated 2 reacts with PCI3 to give a four-membered P2N2 ring 11, and with 2-methyl-2-propenal to give two isomeric (2 + 4) cycloadducts 12 and 13. The silicenium ylid formed initially by thermal elimation of LiF from lithiated 2 in PE/THF cross-dimerises to give a Si2N2 ring 14. If the reaction is carried out in n-heptane, the product after recrystallisation from acetone, 16, is an isomer of 14. The crystal structures of 14 and 16 have been determined.

	Title	P(C6H5)4[VOBr4]: Synthese, IR-Spektrum und Kristallstruktur P(C6H5)4[VOBr4]: Synthesis, IR Spectrum and Crystal Structure
	Abstract	PPh 4 [VOBr4] was prepared by the reaction of PPh4Br with VOBr3 in CH2Br2 solu-tion. The structure of the dark violet crystals was determined with X-ray diffraction. PPli4[VOBr4] crystallizes in the space group P4/n with the lattice constants a = 1275.9 and c = 784.5 pm with two formula units per unit cell. The structure type corresponds to the frequently encountered AsPh4[RuNCl4] type. The VOBr4~ ion forms a square pyramid; the V = O bond has a length of 155 pm. In the IR spectrum, the V —O stretching vibration appears at 922 cm -1 .

	Title	Fehlordnung von Kationen und Kristallwasser bei kubischen Alkalitetrabromo-und -iodothallaten(III) Disorder of Cations and Water Molecules in Cubic Tetrabromo-and -iodothallates
	Abstract	Tetrabromo-and -iodothallates(III) of the alkali cations crystallise from aqueous solutions as cubic hydrates MTlX4-nH20 (M = Li, Na, K, Rb, Cs, NH4; X — Br, I; n — 1-2). The tetraiodothallates retain their cubic structure on dehydratisation, while the tetrabromothallates undergo structural changes. The X-ray structure analyses of RbTlBr4 • H20, NH4TlBr4 • 2HoO and KTlBr4 • 2H20 (—50 °C) showed that these com-pounds consist of a three-dimensional framework of TlBr4 tetrahedra and MBrjo ikosahedra which reminds of zeolites. In cavities of this framework 2/3 of the alkali cations and the crystal water molecules are accommodated in a disordered manner.

	Title	Die Kristallstrukturen von PPh4[SnCl3] und PPh4[SnBr3] The Crystal Structures of PPh4[SnCl3] and PPh4[SnBr3]
	Abstract	PPh4[SnCl3] and PPh4[SnBr3] were prepared by reaction of PPh4X with SnX2 in CH2X2 solutions (X — Cl, Br). The vibrational spectra of the [SnX3] e ions show three SnX3 stretching frequencies, which is caused by deviations from the ideal C3v symmetry. In the crystal structure determinations these deviations show up by slightly different Sn-X bond lengths which are explained by differing hydrogen bridges to phenyl-H atoms. The isotypic crystal structures of both compounds were determined and refined from X-ray diffraction data (R values: 0.042 and 0.034). Although triclinic (space group Pi), the structures are closely related to the tetragonal AsPh4[RuNCl4] structure type. Very pure SnBr2 is prepared by the reaction of PPh4[SnBr3] with AlBr3 in CH2Br2 solution.

	Title	Die Kristallstruktur des Cyano-Elpasoliths [N(CH3)4]2CsFe(CN)6 The Crystal Structure of the Cyano Elpasolite [N(CH3)4]2CsFe(CN)6
	Abstract	The crystal structure of the cubic compound [N(CH3)4]2CsFe(CN)6 was determined by X-ray methods: a = 2527.4(6) pm, space group Fd3c, Z = 32, Rg = 0.028 (260 independent single crystal reflections). The resulting distances within the practically undistorted Fe (CN) 6 3 ~ -octahedron are Fe-C = 193.4(6) and C-N = 115.7(7) pm. Compared to the ideal elpasolite structure of space group Fm3m, Z = 4, the octahedra are rotated by 7.4° through their 3 axis. This is discussed as caused by steric requirements of the tetramethyl-ammonium groups (N-C = 148.4(10) and 149.1(38) pm, resp.). Three quarters of them, of which also the hydrogen positions could bo located, are well oriented. The remaining quarter shows orientational disorder to approach similar contact distances as the other N(CH3)4+ ion exhibits between the methyl groups and the nitrogen ends of the anions.

	Title	Metallkomplexe mit Hexamethylentetramin als Ligand, VI [1] Kristallstruktur von Bis-hexamethylentetramin-bisisocyanatokupfer(II), [CU(NCO)2(C6H12N4)2]
	Abstract	Crystals of the complex [Cu(NCO)2(C6Hi2N4)2] could be obtained by reaction of copper-(Il)nitrate, hexamethylenetetramine, and KNCO in CHCI3 as a solvent. The crystals are triclinic, space group Cl, Z = 4, a = 1373.1(9), b = 2083.1(9), c = 642.6(3) pm, a = 91.05(4), ß = 90.54(6), y = 107.39(6)°. The copper atom is bonded to two terminal cyanato groups via the nitrogen atoms, and to two liexamethylentetramine molecules. In the solid state the coordination of the copper atom is, however, tetragonal pyramidal, because there is an additional, rather long bond to one of the hexamethylenetetramine molecules of the neighbouring complex unit, resulting in the formation of chains.

	Title	Na6CoS4 -ein Thiocobaltat mit isolierten CoS4-Anionen Na6CoS4 -A Thiocobaltate with Isolated C0S4 Anions
	Abstract	NaeCoS4 crystallizes in the hexagonal space group P 63111c with a —890.9(2) pm and c = 687.8(2) pm, Z = 2. The crystal structure was determined from four circle diffracto-meter data and refined to a conventional .ff-value of 0.020. NaöCoS4 is isotypic with NaeZnC>4. The crystal structure can be derived from a h.c.p. arrangement of S atoms. Co atoms occupy tetrahedral voids, the resulting CoS4-tetrahedra being almost regular with an average Co-S distance of 235 pm. Na atoms occupy tetrahedral and octahedral voids in the ratio 1:1.

	Abstract	N-Methylpyridinium-diiodocuprate(I), CßHgNCuI^ and dimethyl(3-dimethylamino-2-aza-2-propenyliden)ammonium-diiodocuprate(I), C6H14N3CUI2, are obtained by reacting Cu with C6H8NI3 or C6H14N3I3 in acetone. Both compounds are built up by the organic cations and chains of edge sharing tetrahedra<jo[Cul4/2-]. The iodocuprate(I) anions are in intimate contact with the cations via intermolecular I • • • C interactions. Though nearly the same average Cu-I distance of 267.2 or 268.2 pm was found for both iodocuprate(I) anions there are different Cu-Cu distances (301-354 pm).

The nickel(II) center is in a distorted octahedral environment of a pentadentate TES ligand (N3Ü2)_and a coordinated H20. Na[Cu(TES)] 3H20 crystal-lizes in the triclinic space group P I (C^-No 2) w T ith cell constants a = 747,3(3), b — 1082,6(5), c = 1459,3(9) pm, a = 81,13(5)°, ß = 84,75(4)°, y = 79,39(3)°, and Z = 2. The copper(II) center is in a distorted quadratic pyramidal environment of a pentadentate TES ligand. Each of the complex anions contains one uncomplexed CH2-CH2-SC>3 _ group.

	Title	Cs6Ga2Se6, ein ternäres Selenogallat(III) mit isolierten [Ga2Se6] 6 --Ionen Cs6Ga2Se6, a Ternary Selenogallate(III) with Isolated [Ga2Se6] 6_ Ions
	Abstract	Cs6Ga2Se6 can be prepared from mixtures of Cs2Se and Ga2Se3. The transparent single crystals of the moisture sensitive compound (m.p. 685 °C) crystallize in the monoclinic system with a = 848.0(5), b = 1364.4(5), c = 1111.5(5) pm, ß = 126.22(5)° (T = —150 °C, Z — 2, space group P2i/c). The gallium atoms pairwisely occupy selected tetrahedral holes between layers formed by the cesium and selenium ions. This structural principle leads to the formation of double tetrahedral isolated [Ga2Se6] 6-ions.
