 Title    Kristallstrukturuntersuchung an einem Strontium-Vanadyl-Vanadat: Sr2(V 0 )V 20 8 Crystal Structure Investigation of the Strontium Vanadyl-Vanadate: Sr2( V 0 ) V 20 8  
 Abstract    Single crystals of Sr2(V 0)V 20 8 have been prepared by quenching melts from higher tem­ peratures. This compound represents a new structure type and crystallizes with monoclinic symmetry, space group C |h-I 2 la, a = 6.929, b = 16.246, c = 7.260 A, ß = 115.82°, Z = 4. The point positions occupied by V5+ show tetrahedral coordination. The refinement of the V4+ position led to split positions with acentric orientations of V4+ in the octahedral O2-surrounding. It results in a square pyramidal coordination with one short V -O distance typically for vanadyl groups.

 Abstract    Black single crystals o f Tio^Tao 670 2 have been prepared by C 0 2-LA SER techniques heating a mixture of TiO and Ta20 5 to T > 2000 °C. The titanium tantalum oxide crystallizes with tetragonaj symmetry, space group D 4 h -P 4 2/mnm, lattice constants a = 4.7344(6) A, c = 3.0504(2) A , Z = 2.

 Title    Zur Kristallstruktur von Ce2(W 0 4)3 On the Crystal Structure of Ce2(W 0 4)3  
 Abstract    Single crystals of Ce2(W 0 4)3 have been prepared by crystallisation from molten mixtures of W 0 3 and C e 0 2. The compound shows m onoclinic symmetry, a = 7.813(4), b = 11.720(2), c = 11.586(3), ß = 109.36(3)°, Z = 4, and is isotypic to Eu2(W 0 4)3, but shows large differences of the atomic coordinates especially of oxygen. The crystal structure of Ce2(W 0 4)3 is charac­ terized by W (1)0 4 tetrahedra, square W (2)0 5 pyramids and a distorted capped trigonal prism of oxygen around cerium. The decrease o f the oxidation states of C e4+ or W6+ was proved by thermogravimetric and magnetic measurements as well as by calculations of the Coulomb terms of lattice energy.

 Abstract    PPh4[SnCl3] reacts with Na2S4 in acetonitrile to give the title compound as one of the products.

(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    Single crystals of the new com pounds CuLn2[B20 5]2 (Ln = Er3+(I), Lu3+(II)) were ob­ tained by a B9O 3 flux-technique. They crystallize in the space group C ih -P 2 \lc with I: a = 453.14(6); b = 721.94(5); c = 929.5(4) pm; ß = 90.01(3)°; Z = 2 und II: a = 451.4(4); b = 718.3(1); c = 928.1(3) pm; ß = 90.00(6)°; Z = 2. The compounds are isotypic to CuTm2[B20 5 ] 2 as well as to the mineral Gadolinite (FeY 2 [B eSi0 5 ]2) and exhibit layer like 2.[B20 5]4 --anions consisting of edge sharing B 0 4 -tetrahedra, which form four-and eight-membered rings. The borate anions are separated by layers of elongated C u 0 6-octahedra and slightly distorted tetragonal L n 0 8-antiprisms.

 Abstract    Single crystals of the new compound Cu2C d(B20 5) 0 have been prepared by B 20 3/V 20 5 flux technique in a closed silver tube. Their structure is isotypic with Cu2C o(B 20 5) 0 but its preparation is quite different. X-ray investigations on single crystals led to the space group C |h-P 2 !/c (Nr. 14), a = 339.9(2); b = 1509.8(2); c -927,0(1) pm; ß = 93.19(1)°; Z -4. The structure contains isolated B 2O s groups and oxygen that is not coordinated to boron. Cad­ mium is octahedrally coordinated by oxygen, while copper exhibits a nearly square planar or a fivefold pyramidal coordination.

 Title    Kristallstrukturuntersuchung an einem bismuthaltigen Hollandit: Crystal Structure Investigation of the Bismuth Containing Hollandite: Bij 9Cu4V40 16  
 Abstract    Single crystals of B^ 9Cu4V 4O i6 have been prepared by quenching of CO2-LA SER heated samples. They were investigated by X-ray techniques. The compound^ crystallizes with tetra­ gonal symmetry, space group C4h-I 4 /w , a = 9.945(2) A, c = 2.915(3) A, Z = 1, and is isotypic to the mineral Hollandite. B^ 9Cu4V4O i6 is the first Hollandite with a statistical distribution of vanadium and copper in the network o f octahedra. Calculations of the Coulomb terms of lattice energy led to a distance o f bismuth to the lone pair of 1.07 A. Considering the lone pair as part of the coordination sphere of Bi3+ a square pyramidal polyhedron is obtained.

 Abstract    The compounds EtPh3PI3, EtPh3PI5 and EtPh3PI7 have been prepared by the stoichiometric reaction of EtPh3PI with iodine in a mixture of dichloromethane and ethanol. EtPh3PI3 cry­ stallizes in the monoclinic space group P2,/n with a = 1176.7(3) pm, b = 1202.5(3) pm, c = 1565.9(4) pm, ß = 93.22(2)° and Z = 4. The crystal structure has been refined to R f =0.043 for 3394 reflections. EtPh3PI5 crystallizes in the monoclinic space group I2/a with a = 1913.9(4) pm, b = 1239.0(2)pm, c = 2435.1(4) pm, ß = 115.84(1)° and Z -8 . The crystal structure has been refined to R f = 0.052 for 3043 reflections. EtPh3PI7 crystallizes in the orthorhombic space group Pbca with a = 1702.7(4)pm, b = 1952.5(4) pm, c = 1809.8(4) pm und Z = 8 . The crystal structure has been refined to R f = 0.053 for 3208 reflections. The structures may be described as layerlike packings of cations Ph3EtP+ and of anions If , I f and I f , respectively. The isolated triiodide ion If is slightly asymmetrical and slightly bent as expected. The pentaiodide ion If forms iodine ribbons like a rope ladder. The heptaiodide ion I f is composed of pentaiodide groups and iodine molecules connected to puckered anionic layers.

 Abstract    Single crystals of the so far unknown compounds KCuGd2M o4O t6 (I) and KCuTb2M o40 16 (II) have been prepared by flux technique. The compounds crystallize with monoclinic sym­ metry. space group C^h-C 2 /c with (I): a = 5.278(2), b = 12.666(5), c = 19.604(14) Ä; ß = 92.76(6)°; (II): a = 5.259(13), b = 12.616(3), c = 19.556(9) A, ß = 92.93(4)°, Z = 4. M olyb­ denum exhibits tetrahedral coordination. The surroundings of copper can be described by distorted tetrahedra, capped by two more distant oxygen atoms, and the rare earth ions show a square antiprism. Potassium is inside an irregular polyhedron. The relationship of the structures o f (I) and (II) is discussed with respect to the KLnMo2Os type compounds. Coulomb term calculations of the lattice energy indicate an oxidation state of copper higher than Cu1.

 Abstract    Single crystals of NaFe3V30 12 have been prepared by solid state reaction below the melt­ ing point of the reaction mixture. This compound is isotypic to the mineral Howardevansite but shows lower triclinic symmetry, space group C }-P 1 , a = 6.757(2), b = 8.155(2), c = 9.816(3) Ä, a = 106.05(2), ß = 104.401(9), y = 102.09(2)°, Z = 2. The acentric space group is caused by the sodium positions, all other atoms comply with the space group PI of Howarde­ vansite. The different ions are coordinated by O2-forming V 0 4 tetrahedra, FeOfi octahedra, trigonal FeOs bipyramids and irregular NaOs and NaOy polyhedra, respectively. The crystal chemistry is discussed with respect to Howardevansite.

It is isotypic with Ba4NaCu0 4(C03)2 and shows Li+ with octahedral and Cu3+ with square planar coordina­ tion by O2-. The crystal structure are discussed with respect to the related compounds Ba4N aA u 04(0 2)2 and Ba4K A u04(

 Title    Uber einen Lanthanoid-Mangan-Apatit: Nd4M n(Si04)30 On a Lanthanoid Manganese Apatite: Nd4M n(S i04)30  
 Abstract    Single crystals of Nd4M n (S i0 4)30 have been prepared by a Bi20 3 flux in closed copper tubes. The colourless crystals show hexagonal symmetry, space group C |h-P 6 3/m, a -9,4986(9), c = 6,944(2) A, Z = 2. Nd4M n (S i0 4)30 crystallizes in the A patite structure and shows Nd3+ and Mn2+ with partly statistical distribution. A s a consequence of this, 0 (2) and 0 (4) are occupying split positions.

 Title    Kristall-und Molekülstruktur von 2-[3-(N,N-Diethylammonium)propylimino]-2-phenyl-dithioacetat Crystal and Molecular Structure of 2-[3-(N,N-Diethylammonium)propylimino]-2-phenyl-dithioacetate  
 Abstract    The title compound, formed by the reaction o f acetophenone with 3-diethylamino-1-propylamine and sulfur, crystallizes in the orthorhombic space group P 2 12 12 1 (Z = 4) with lattice constants a = 818.1(2) pm, b -1225.1(2) pm and c = 1622.4(4) pm. The characterization of the molecule as a zwitterion is established by the observed bond parameters. Both spec­ troscopic investigations and the results of the X-ray structure determination show that a hydrogen atom is bonded to the amino nitrogen rather than to the imino nitrogen.
