 Title    Eine neue Verbindung im System Ba/Ln/Zn/Pt/O: Bs^Sn^Zi^PtOis On a New Com pound in the System B a/Ln/Zn/Pt/O : Ba4Sm 4Z n3P tO |5  
 Abstract    Reactions of mixtures of B aC 03, ZnO, Sm20 3 (3:5: 1) heated in platinum crucibles up to 1250 °C led to big black single crystals of Ba4Sm4Zn3P t0 15. The new compound crystallizes with hexagonal symmetry, space group C^-Pö^mc, a = 1 L657, c = 6,789 A , Z = 2. It is isotypic with Ba6Nd2Al4O l5 but shows an ordered Pt4+ and Zn2+ distribution over the aluminium positions. The octahedrally coordinated barium sites of the Ba6Nd2Al40 15 type are occupied by Sm3+. In comparison to compounds of the composition Ba6Ln2M40 15 (M = Al, Fe, Co), Ba4Sm4Zn3PtOi5 is the first example containing different oxidation states at the M '+ positions.

 Title    Zur Kenntnis eines Barium-Lanthanoid-Aluminat-Zinkats: BaLuAlZn30 7 mit einem Anhang zu Ba2Er2Zn80 13  
 Abstract    Reactions of B aC 03, ZnO, Lu20 3 and A120 3 mixtures at temperatures up to 1500 °C led to small and colourless rods of BaLuAlZn30 7. The new compound crystallizes with hexagonal symmetry, space group CöV -P63mc, a = 6.273, c =10.161 A, Z = 2. In spite of small differences in the oxygen content BaLuAlZn30 7 is isotypic to Ba2Ln2Zn80 13. The crystal structure shows Zn2+ with tetrahedral, Lu '+ with octahedral and Ba:+ with anticuboctahedral coordination by 0 2~. It has been shown that parts of the [Zn3A107]5_ network are fragments of the ZnO structure. In consequence one oxygen atom is fourfold coordinated by zinc/aluminium. The space group of Ba2Ln2ZnxO i3 must be corrected to C6V -P63mc.

 Title    Electrochemistry of Oxygenation Catalysts, Part 6* Electrosynthesis, Structure, Analytical and Electrochemical Properties of Monomeric [Coin(salen)(DMF)2]+ X' Salts (X = PF6, C104)  
 Abstract    Electrochemistry [CoH1(salen)(DMF)2]+ X" salts [X = PF6, C104; salen = bis(salicyliden)ethylendiiminato; DMF = dimethylformamide] have been synthesized by electrochemical and chemical (air) oxidation of Co"(salen). Their monomeric structure with two DMF molecules in the axial positions in both the solid state and DMF solution is shown by X-ray crystal structure analysis, thermal analysis, mass spectroscopy, and 'H and l3C NMR spectroscopy. The electrochemical reduction of the [Coni(salen)(DMF)2]+ cation is investigated by cyclic voltammetry and com­ pared to the oxidation of the neutral CoH(salen). The redox reaction connecting the cobalt(II) and the cobalt(III) species appears to be a quasi-reversible electron transfer. These properties make the [Co1 1 (salen)(DMF)2]+ X-salts starting materials for the analysis of the interaction of basic substrates with cobalt(III) species in the context of the biomimetic oxygenation reactions catalyzed by such complexes.

 Title    The Crystal Structure o f /?-CsI04, the Room-Temperature Modification o f Cesium Periodate  
 Abstract    The crystal structure of /?-CsI04, the room-tem-perature modification o f cesium periodate, was determined as orthorhombic, space group Pnma, with a = 5.8644(5), b = 6.0326(4), c = 14.379(1) A and Z = 4. The structure was refined to = 0.0309, wR2 = 0.0701 for 425 absorption-corrected reflections. /?-CsI04 is isostructural with yS-CsRe04. The structure comprises isolated I 0 4 tetrahedra, linked together by Cs ions. The average 1-0 dis­ tance was found to be 1.747 A .

 Title     
 Abstract    Single crystals of BaCuTe03T e 0 4 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group C2v-Ama2, a = 5.4869(8), b = 15.412(1), c = 7.2066(4) A , Z = 4. This compound represents a new structure type, containing B aO 10, C u 0 5, T e 0 6 and T e 0 4 polyhedra. The lone pair (E) of TeIV completes the TeIV0 4 polyhedron to a trigonal T e 0 4E bipyramid. The Te to E distance is estimated by calculations o f the Coulomb terms of lattice energy to 1.43 A .

 Title    Dicyanometallate, VII [1] Darstellung und Kristallstruktur von Gadolinium-tris-dicyanoaurat (I), Gd[Au(CN)2]3-2,3H20 Dicyano Metallates, VII [1] Preparation and Crystal Structure o f Gadolinium-tris-dicyanoaurate (I), Gd[Au(CN)2]3 -2,3H20  
 Abstract    The title compound has been prepared by adding a stoichiometric amount of gadolinium nitrate hexahydrate to an aqueous solution of potassium dicyanoaurate(I). Single crystals could be obtained by slow evaporation from the saturated solution. The compound crystallizes hexa-gonally, space group P-62m, with a = 6.6319(6), c = 9.108(2) Ä, c/a = 1.3734 and Z = 1. The structure comprises layers of considerably bent dicyanoaurate groups. The gold atoms form a nearly regular 3.6.3.6 -Kagome net with a layer sequence AA.. and an Au -Au distanceoof 3.316(2) A, i. e. remarkably shorter than that found in KAu(CN)2 (Au -Au = 3.652(1) Ä). Above and below the gold layers, the terminal nitrogen atoms of the dicyanoaurate groups build up a two-dimensional net work in the a,b plane, thereby creating trigonal-prismatic holes, which are occupied by the gadolinium ions. Up to three water molecules per unit cell complete the coordination sphere around the gadolinium ion to form a tricapped trigonal prism. The analogous compounds with Ln = Sm, Eu, Tb and Dy are obviously isostructural with the Gd compound, as can be inferred from preliminary X-ray studies.

 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.

 Abstract    Phenylsulfinic acid C6Fr5S 0 2H crystallizes in the orthorombic space group Pna21, a = 734.3(4), b = 579.9(5), c = 1476.5(9) pm, with four formula units per unit cell. The configuration of the sulfur atom is pyramidal. The molecules form infinite chains via strong hydrogen bonds. The Raman spectra of CA H5S 0 2H and C6H5SOCl are reported and discussed.

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.
