	Title	Zur Synthese und Kristallstruktur von Bariumboroarsenat Ba(BAs05) mit einem Beitrag über Bariumorthoarsenat Ba3(As04)2 Synthesis and Crystal Structure of Barium Boroarsenate B a(B A s05) with a Contribution on Barium Orthoarsenate Ba3(A s0 4)2
	Abstract	Single crystals of Ba(BAs05) (I) and Ba3(As04)2 (II) were obtained by melting B20 3, arsenic pentoxide and BaO at 1100°C. Both compounds crystallize trigonally, space groups (I): C3 -P3t (Nr. 144), (II): D3d -R3m (Nr. 166), with the lattice parameters (I): a = 726.7(1), c = 710.6(1) pm, Z = 3 and (II): a = 576.7(1), c = 2116.3(2) pm, Z = 3. Ba(BAsOj) is isotypic to Pb(BAs05) (Stillwellite structure) and Ba3(As04)2 to Ba3(P04)2. The structure of Ba(BAs05) is characterized by helical chains of rings of two borate tetrahedra and one arsenate tetrahedron. Barium is tenfold coordinated by oxygen. A rod-like sequence of coordination polyhedra, A s04-Ba(2)O\|0-Ba(1)O\|2-Ba(2)O\|0-AsO4 is characteristic in the crystal structure of Ba3(A s04)2.

	Title	Synthese und Kristallstruktur von (TeCl3)2MoCl6 und /?-(TeCl3)2ReCl6 Synthesis and Crystal Structure of (TeCl3)2M oCl6 and /?-(TeCl3)2ReCl6
	Abstract	Single crystals of (TeCl3)2M oCl6 and /?-(TeCl3)2 ReClft are obtained by the reactions of TeCl4 with MoC14 at 195 °C and o f TeCl4 / Te with ReCl5 at 150 °C, respectively. The com pounds form dark-red moisture sensitive crystals. The crystal structure determinations show, that both crystallize isotypically (rhombohedral, space group R 3, (TeCl3)2M oCl6: a = 1116,9(1), c = 3539,5(5) pm. 1966 unique reflections for 69 parameters, final R = 0.058; /?-(TeCl3)2ReCl6: a = 1113,3(3), c = 3546(2) pm. 1653 unique reflections for 70 parameters, final R = 0.034). The structures consist of octahedral MC162_ anions (with M =M o,Re) and pyramidal TeCl3+ cations. The ions are interconnected through long Te-Cl bridges (2 9 1 ,1 -295,6 pm) to give distorted TeClA octahedra. MC16 and TeCl6 units are connected via edges and corners, resulting in a complex layer structure with layers parallel to the ab-plane. In the previously reported a-form of (TeCl3)2R eCl6, only connections via corners are observed.

	Title	A -P r 2S3, D -H o2S3 und E -Y b 2S3: Synthese und Einkristallstrukturuntersuchungen
	Abstract	The oxidation of reduced chlorides (MC12) or chloride-hydrides (MC1HV) of the lanthani des with sulfur (700-850 °C, 7 d, sealed tantalum capsules or evacuated silica vessels) usually results in the formation of the sesquisulfides M2S3 as the main products. In the presence of appropriate fluxes (e.g., alkali halides), the products often are obtained as single crystals, and the flux decides which modification is favoured. Ternary halides of the trivalent lanthanides with the corresponding alkali metal can mostly be found as the second components. Crystal growth and structural investigations of thus produced single crystals of Pr2S3 (from PrClH() 67 + S + NaCl, 5:5:1, A type: orthorhombic, Pnma (No. 62), Z = 4, a = 748.22(5), b = 405.51(3), c = 1560.74(9) pm, R = 0.024, Rw = 0.020), Ho^S, (from U -H o^S , + KI, 1:1, D type: mono clinic, P 2xim (No. 12), Z = 6, a = 1746.15(9), b = 400.23(3), c = 1012.43(6) pm, ß = 98.529(4)°, R = 0.041, Rw = 0.035), and YbiS3 (from T-Yb^S^ + KI, 1:1, E type: trigonal, R 3c (No. 167), Z = 6, a = 674.97(2), c = 1820.11(9) pm'. R = 0.019, Rw = 0.018) are reported here. In accordance with the lanthanide contraction, the trivalent cations (M3+) exhibit sulfur coordination numbers of 7 and 8 in A -P r 2S3, 6 and 7 in D -H o 2S3, and 6 in E -Y b 2S3 (corundum-type structure).

The crystals are tetragonal, space group 14j/a, with a = 5.9868(7), c = 10.043(1) A, c/a = 1.678 and Z = 4. CaAu20 4 is isostructural with LaPd20 4, SrAu20 4 and BaAu20 4. Its structure comprises square-planar A u 0 4 groups (< A u -0 > = 2.007 A), which are stacked into columns along [100] and [010], These columns are connected by shared corners forming a three-dimensional framework. The Ca ions are situated in tunnels created by the gold-oxygen partial structure. They are surroun ded by eight oxygen atoms (< C a -0 > = 2.490 A) in a slightly distorted dodecahedron.

Their metal chelate complexes with Cu, Ni and Co are described. The molecular structures of bis[N-(pyrrol-l-yl)salicylaldim inato]copper(lI) la, bis{N-[3-(pyrrol-l-yl)propyl]-salicylaldiminato}nickel(II) 2b and tris{N -[3-(pyrrol-l-yl)propyl]salicylaldiminato}cobalt(III) 2d were determined by X-ray structure analysis. The chelates with tetracoordinated copper and nickel show a square planar coordination with the characteristic trans configuration. The chelate with hexacoordinated cobalt has a meridional coordination sphere. The complexes have also been investigated by X-ray absorption spectroscopy (X-ray Absorption Near Edge Structure, XANES) at the K edges of the 3d metals. Analyzing the relative intensities of the Is — 3d pre peak and the K edges of the line shape, it was possible to distinguish between planar, tetrahedral and octahedral coordination of the chelates.

The chlorides were prepared by the reaction of (M e2S)AuCl with equimolar amounts (or with an excess) of the corresponding isonitrile. The bromides, iodides and thiocyanates were obtained from the reaction of (RNC)AuCl with K+X -(X = Br, I, SCN) in the two-phase system H2O/CH2CI2. The molecular and crystal structures of la. 2b. 3a-c, 4a, and 5a-c have been determined by X-ray diffraction methods. In the solid state the molecules are aggregated through short A u-A u contacts into dimers (4a and 5c), chains (la , 2b and 3a-c) or sheets (5a and 5b). The influence of the isonitrile and halide ligands on the type and strength of the intermolecular A u-A u contacts is discussed. I n tro d u c tio n

	Title	Polynuclear Gold Complexes of the Carbodiimide Unit [N=C=N]2
	Abstract	The reaction of N,N'-bis(trimethylsilyl)carbodiimide with equimolar quantities of tris[(triphenylphosphine)gold]oxonium tetrafluoroborate in dichloromethane at -40°C gives high yields of a trinuclear complex {[(Ph3P)Au]2NCN[Au(PPh3)]}+ BF4~(1). According to variable temperature NMR data the cation is fluxional in solution with a rapid site exchange of the [(Ph3P)Au] units, but has an unsymmetrical (N,N,N') low temperature ground state configu ration. A single crystal X-ray diffraction study has shown that in the crystal lattice these cations are associated further into cyclic, hexanuclear dimers through two short head-to-tail Au-Au contacts (auriophilicity). Treatment of complex 1 with one equivalent of [(Ph3P)Au]+ BF4_ in tetrahydrofuran affords a tetranuclear complex {[(Ph3P)Au]2NCN[Au(PPh3)]2}2+ 2BF4_ (2). The ambient temperature NMR spectra of 2 suggest a fluxional, pseudo-symmetrical structure, but at low temperature a set of three 11P signals (1:2:3 intensity) indicates an aggregation into higher nuclearity species with non-equivalent [Au(PPh3)] units.

	Title	The Stannides EuPdSn and EuPtSn
	Abstract	EuPdSn and EuPtSn were prepared from the elements in tantalum tubes at 1070 K and in vestigated by X-ray diffraction on both powder as well as single crystals. They crystallize with the TiNiSi type structure of space group Pnma and with Z = 4 formula units per cell. Both structures were refined from single-crystal diffractometer data: a = 751.24(9), b = 469.15(6), c = 804.31(9) pm, V = 0.2835(1) nm3 for EuPdSn, and a = 753.38(7), b = 467.72(4), c = 793.08(7) pm, V = 0.2795(1) nnr for EuPtSn. The structures consist of three-dimensional [PdSn] and [PtSn] polyanionic networks in which the europium atoms are embedded. The crystal chemistry of these stannides is briefly discussed.

R\ =0.0232). The title compounds are isostructural with La4Au20 9. Their structure comprises isolated square-planar A u04 groups, stacked along [010] to form a columnar structure. The Au-Au distance along the columnar direction is 3.10 A. Structural relations to Bi2C u04 und (Nd, Pr)2A u05 are discussed. Hochdrucksynthese und K ristallstruktur von Nd4Au2 C>9 und Gd4Au2 C>9

	Title	Zwei monokline Kupfer-Oxovanadate des Magnesiums mit geordneter Metallverteilung: /w-Mg2CuV20 8 und MgCu2V20 8. Ein Beitrag zur Dimorphie von Mg2CuV2Os Two Monoclinic Copper Oxovanadates of Magnesium Showing Ordered Metal Distribution: m-Mg9CuV-,08 and MgCu
	Abstract	Single crystals of ra-Mg2CuV20 8 (I) and MgCu2V20 8 (II) have been prepared by solid state reactions. The orange (I) and dark red (II) crystals show monoclinic symmetry, space group C2h -P2,/c, (I): a = 6.167(3), b = 8.172(5), c = 6.400(8) Ä, ß = 116.22(3)°, Z = 2; (II): a = 6.453(1), b = 8.342(2), c = 11.517(2) Ä, ß = 90.44(2), Z = 4. Both compounds show ordered metal distributions and vanadium in tetrahedral coordination by oxygen. (I) is characterized by elongated C u06 octahedra and (II) by trigonal C u 0 5 bipyramids. ra-Mg2CuV20 8 is the low temperature form of the formerly investigated orthorhombic o-Mg2CuV2Ö8. Calculations of the Coulomb parts of the lattice energy of the two crystal forms are discussed.
