 Title    Synthese und Kristallstruktur des Lanthan-Titanat-Tellurats LaTi  
 Abstract    (Ti0 2 5Te0j 5)O6 und seine Verwandtschaft mit PbSb20 6 und Sr(MnTe)06 Synthesis and Crystal Structure of the Lanthanum Titanate Tellurate LaTi(Ti0 25Te0 75) 0 6 and its Relationship to PbSb20 6 and Sr(M nTe)06 L. Single crystals of LaTi(Ti0 25T e o .75) 0 6 have been prepared by solid state reactions. X-ray investigations led to trigonal symmetry, space group C3-P3 , a = 5.141(10), c = 5.218(10) A, Z = 1. The compound is characterized by a predominantly ordered distribution of Ti4+ and Te6+. Typical features of the crystal structure are staggered layers containing edge connected T i0 6 and (Ti,Te)06 octahedra. The layers are connected by La3+ ions receiving an octahedral coordination by the surrounding oxygen ions. The relationships to the PbSb20 6 type and the recently described compound Sr(M nTe)06 are discussed.

 Title    Synthese und Charakterisierung des Fulleren-Kokristallisats C60*SiH(C6H5)3 Synthesis and Characterisation of the Fullerene Co-Crystal C60*SiH(C6H5)3  
 Abstract    A new fullerene co-crystal C60*SiH(C6H5)3 has been synthesized by crystallisation from a melt of SiH(C6H5)3 and C60 in sealed duran tubes at 80°C. X-ray investigations led to triclinic symmetry, space group P i, a = 10.086(1),/? = 14.431(2), c = 14.911(2) Ä, a = 79.13(1), ß = 74.943(9), 7 = 88.33(1)°, V = 2058.0(4) A 3, Z = 2. The crystal structure consists of isolated fullerene and silane molecules. At -80°C, C60 is still rotationally disordered. Temperature dependent Guinier powder diagrams do not show any phase transformation between 25 and -165°C. The compound is stable in air.

 Title    Isolierte trigonale S r 0 6-Prismen verknüpfen Kagome-Netze im Strontium-Manganat(I V)-Tellurat( VI): SrMnTe06 Kagome Layers Connected by Isolated Trigonal Sr06 Prisms in the Strontium Manganate(IV) Tellurate(VI): SrMnTe06 L  
 Abstract    Single crystals of the hitherto unknown compound SrM nT e06 have been prepared from Sr(0H)2-8H20 , M n C 0 3(aq) and T e 0 2 in air by crystallization below the melt range. X-ray in­ vestigations showed hexagonal symmetry, space group D3h-P62m, lattice constants a = 5.143(1), c = 5.384(2) A, Z = 1. SrM nTe06 is characterized by staggered [(Mn/Te)60 18] Kagome layers along [001]. These layers are connected by Sr2+ ions, resulting in S r0 6 prisms isolated from each other. The structure is discussed with respect to the connection of Kagome nets in the quaternary oxides of the Ba3Ln40 9 type.

 Title    Uber CuDy2[B80 16] und CuHo2[B80 16]: Zwei neue "Metaborate" mit einem ^ [B80 16]g_-Anion On CuDy2[B80 16] and CuHo2[B80 16]: Two New "Metaborates" with a ^ [B80 16]8-Anion  
 Abstract    Nearly colourless single crystals of the compounds CuDy2 [B80 i 6] (I) and CuHo2[B80)6] (II) have been obtained by a B20 3 flux technique. They crystallize in the structure of CuTb2 [B80)6] (I) or in an orthorhombic variant (II). X-ray investigations on single crystals led to the space group C2h -P2!/c (Nr. 14) with lattice parameters a = 1025,5(10); b = 836,99(10); c = 621,2(8) pm, ß = 90.47(10)°; Z = 2 (I) and D^h -Pbam (Nr. 55) with a = 840,7(2), b = 616,6(2), c = 1022,0(2) pm, Z = 2 (II). The structures contain 1 [B80 16]8_ chains isolated from each other, which include tri-and tetracoordinated boron, T'fie chains consist of alternating twelve and eight-membered rings of boron and oxygen atoms connected by B 0 4 units. Dy,+ and H o 3+ are octacoordinated and Cu2+ is hexacoordinated in elongated octahedra by oxygen. The relation between these two structures is discussed.

 Title    CuHo2[B20 5]2* Ein unerwarteter Strukturtyp in der Reihe der Kupferlanthanoidborate CuHo2[B20 5]2: An Unexpected Structure Type in the Series of Copper  
 Abstract    Single crystals of the new compound CuHo2 [B20 5 ]2 were obtained by using a B20 3 flux technique with CuO and Ho20 3 at 1050 °C. X-ray investigations on single crystals led to the space group P 2,/c (Nr. 14) with lattice parameters a = 454.3(2); b = 726.0(4); c = 936.0(5) pm; ß = 90.77(1)°; Z = 2. The compound is isotypic to CuTb2[B20 5 ] 2 as well as to the gadolinite structure (FeY2 [BeSi05]2). The structure exhibits layer-like 2 [B20 5]4~, a two-dimensional anion consisting of edge sharing B 0 4 -tetrahedra, which form four-and eight-membered rings. The layers are connected by elongated C u06-octahedra and slightly distorted tetragonal LnOs-antiprisms.

 Title    The Crystal Structure of the Potential Ferroelectric Calcium Rhenate(VI, VII) CanRe4 0 24 and its Relation to the Structure of S rn 0 s40 24  
 Abstract    The title compound was prepared in well-crystallized form by thermal decomposition of Ca5Re20i2. Its structure was determined from single-crystal X-ray diffractometer data: /4 j, a = 1107.0(1), c = 1609.3(1) pm, Z = 4, R -0.056 for 4565 structure factors and 119 variable parameters. The calcium atoms occupy seven different sites with 8, 9, or 10 oxygen neighbors. The two different rhenium atoms are octahedrally coordinated by oxygen atoms with average Re-O distances of 193.1 and 187.7 pm for the six-and seven-valent rhenium atoms, respectively. The compound shows Curie-Weiss behavior with a magnetic moment of n exp = 1.15(±0.10) Pb per Re(VI) atom. The structure is closely related to that of Srn0s4024 which, however, crystallizes in the space group I2la. The difference between the two structures arises through the higher coordination numbers of the strontium atoms. It is suggested that at high temperature both compounds crystallize in the common higher symmetry space group I4\/a. Since CanRe4024 crystallizes in the pyroelectric class 4 this compound is expected to be ferroelectric.

 Abstract    Single crystals o f Ag2C s[B ,50 24] were prepared by using a B 20 3 flux technique with Ag2C 0 3 and Cs2C 0 3 in a closed silver tube at 650 °C. X-Ray investigations led to a new crystal structure in the space group P 2 ,2 ,2 (Nr. 18) with lattice parameters a = 1778.7 (4); b = 2219.2 (4); c = 512.2 (1) pm, Z = 4. The silver atoms are part of distorted A g 0 4 tetrahedra and planar A g 0 3 units while the caesium atoms are eightfold coordinated by oxygen. The compound contains an as yet unknown borate anion [B,50 24] with twelve B 0 3-and three B 0 4 units per formula. The B 0 3 units are connected to eight cords twisted to helices which are combined via B 0 4 tetrahedra to a three dimensional framework with large tunnels occupied by the cations.

K opp, B e rn h a rd N eu m ü ller* Single crystals of [M o(CO)3(NCM e)(S'Bu)]2 (1) and [{Mo(CO)3}2{Mo(CO)2}{S'Bu}4] (2) were obtained by the reaction of [M o(CO)3(NCM e)3] with [(PhCH2)2GaS'Bu]2 in 1,4-dio-xane. The X-ray structure determination of 1 showed the presence of a Mo2S2 four-membe-red ring with a Mo-Mo bond length of 296,7(1) pm. Space group Pbca, Z = 4, lattice dim en­ sions at -80 °C: a = 1588,2(3), b = 905,8(1), c = 1676,0(1) pm, R y = 0,0555.

 Title    Indium partiell in tetraedrischer Sauerstoffkoordination in BaIn2Zn30 7 . Eine Betrachtung zum Ba2Ln2Zn80 13/BaLnAlZn3 0 7 -Typ Partial Tetrahedral Oxygen Coordination of Indium in BaIn2Zn30 7. A Consideration of the Ba2Ln2Zn80 13/BaLnAlZn30 7 Type O  
 Abstract    Single crystals of BaIn2Zn30 7 have been prepared by solid state reaction and crystallization from flux. X-ray investigations led to hexagonal symmetry, space group C6V-P6 3mc, lattice constants a = 6.342(1), c = 10.282(1) A, Z = 2. BaIn2Zn30 7 shows tetrahedral positions statistically occupied by In3+ and Zn2+. The crystal structure is isotypic to Ba2Ln2Zn80 13 and BaLnAlZn30 7. A discussion of the related compounds is given.
