 Title     
 Abstract    uT m 2[ B 20 5] 2: D as erste "M etaborat" mit einem x [ B 20 5] 4 -Anion CuTm2[B20 5]2: The First " Metaborate" with a ^ [ B ^ s ] 4 -Anion Single crystals o f the compound CuTm2[B 20 3]2 were obtained by a B20 3 flux technique. The compound contains a hitherto unknown metaborate anion with the formula ^ [ ^ O s ] 4-. It crystallizes in the monoclinic space group C|h-P2!/c with a = 452.18(7); b = 720.0(2); c = 929.2(5) pm; ß -90.16(5)°; Z = 2. The metaborate layers consists of four and eight membered rings of edge-sharing B 0 4-tetrahedra resembling the complex anion in the isotypic gadolinite structure of F e Y 2[B eS i0 3]2. The layers are connected via copper-centered elongated oxygen octahedra and slightly distorted thulium-centered tetragonal oxygen antiprisms.

 Title    Tetraphenylphosphonium- tris(tetrasulfido)stannat, (PPh4)2[Sn(S4)3] Tetraphenylphosphonium Tris-tetrasulfido- stannate, (PPh4)2[Sn(S4)3]  
 Abstract    PPh4[SnCl3] reacts with Na2S4 in acetonitrile to give the title compound as one of the products. Its crystal structure was determined by X-ray diffrac­ tion (R = 0.071 for 3288 reflexions). Crystal data: monoclinic, P2JC, Z = 4, a = 1301.2(3), b = 1139.1(2), c = 3476.2(7) pm, ß = 97.82(3)°. (PPh4)2[Sn(S4)3] is isotypic with (PPh4)2[Sn(Se4)3] and contains [Sn(S4)3]2-ions in which three tetra-sulfido groups are chelating an octahedrally coordi­ nated tin atom.

 Abstract    The new compounds A4[Nb6Cli2(N3)6](H:0)2 (A = Rb, Cs) were synthesized from In4[Nb6Cli2Cl6] by substituting six terminal Cl ligands and the In+ ions in methano-lic solution. An X-ray structure refinement was performed on single-crystal data of Rb4[Nb6Cli2(N3)6](H?0)2 (1) (space group Pi, Z = 1, a = 912.5(1) pm, b = 937.2(1) pm, c = 1062.0(1) pm, a = 96.88(2)°, ß = 101.89(1)°, 7 = 101.44(2)°) and Cs4[Nb6Cli2(N3)6](H20)2 (2) (space group PI, Z = 1, a = 920.9(5) pm, b = 947.9(7) pm, c = 1091.8(7) pm, a = 96.89(6)°,/?= 103.35(5)°, 7 = 101.60(5)°. Each of the centrosymmetric [Nb6Cli2(N3)6]4~ ions of the isotypic compounds contains six terminal azide groups at the corners of the octahedral niobium cluster (dfvj^N = 226(1) pm (1), 225(1) pm (2), bond angles Nb-N-N 120-127°). The [Nb6Cli2(N3)6]4_ ions are linked via Rb-N and Rb-Cl interactions of the Rb+ ions to form a three-dimensional structure. Crystals of the compounds react explosively on heating or mechanical pressure. Die Synthese und Struktur von Clusteraziden:

 Title    [Ni2(SC4H9)6]2-> ein neuartiger zweikerniger Nickel-Thiolato-Komplex mit kantenverknüpften NiS4-Tetraedern und [Ni(SC6H4SiMe3)4]2-, ein strukturchemisch verwandtes einkerniges Komplexion [Ni2(SC4H 9)6]2~, a Novel Binuclear Nickel-Thiolat Complex with NiS4 Tetrahedra Sharing Edges and [Ni(SC6H4SiMe3)4]2_, a Structurally Related M ononuclear Complex Ion  
 Abstract    Reaction of nickel(II) chloride with sodium or potassium tert-butane thiolate in acetonitrile affords the isotypical compounds [Nb(SrC4H9)6]Na2 • 4 MeCN (1) and [Ni7(SfC4H9)6]KT • 4 MeCN (2), respectively. Crystal data: 1: a = 9.859(3), b = 11.877(3), c = 19.675(5) Ä , ß = 96.11(2)°, space group P 2x/n, Z = 2:2: a = 9.854(2), b = 11.915(3), c = 20.558(5) Ä , ß = 99.62(2)°, space group P 2xln, Z = 2. The structures were refined to R = 0.0599 (1) and 0.0562 (2), respectively. Both compounds contain the complex ion [Ni2(SrC4H 9)6]2_ (3), which is not only the first example of a tetrahedral nickel complex with alkane thiolate ligands, but also the first poly-nuclear nickel complex containing tetrahedral NiS4-units sharing a comm on edge. Reaction of nickel(II) chloride and sodium (2-trim ethylsilyl)thiophenolate in acetonitrile leads to [Ni(SC6H4SiM e3)4]2~ (5) with tetrahedral stereochemistry. The m ononuclear complex ion is isolated aso [Ph4P]2[Ni(SC6H4SiM e3)4]-5M eC N (4) with a = 13.771(2), b = 14.163(2), c = 25.873(4) A , a = 77.44(1), ß = 75.13(1), y = 72.46(1)°, space group P 1 and Z = 2. The final refinement converged to R = 0.0445.

Kristallstruktur von Bis-(N,N-diethyl-N'-ferrocenoylthioureato)nickel(II) N,N-Disubstituted N'-Ferrocenoyl Thioureas as Bidentate Ligands for Transition Metal Ions. Crystal Structure of Bis-(N,N-diethyl-N'-ferrocenoylthioureato)nickel(II)  
 Abstract    N,N-diethyl-N'-ferrocenoyl-thiourea and N-(morpholino-thiocarbonyl)ferrocenecarboxylic amide have been prepared by the reaction of ferrocenoyl chloride with potassium thiocyanate and the respective amine in dry acetone. These bidentate ligands yield neutral heterometal-lic complexes with Ni(II), Cu(II), Mn(II) and Co(III). The dark brown air stable crystals of bis-(N,N-diethyl-N'-ferrocenoylthioureato)nickel(II) were characterized by X-ray structure de­ termination. Lattice dimensions: a = 1870.9(1), b = 1161.5(1), c = 1491.4(1) pm; space group Pca2!, Z = 4, R = 0.030 for 5707 observed reflections.
