 Title    Über Oxocuprate, XIV Zur Kristallchemie von Sr2Cu304Cl2 On Oxocuprate, XIV On the Crystal Chemistry of Sr2Cu304Cl2  
 Abstract    The new compound Sr2Cu304Cl2 was prepared in melts of SrCl2. A single crystal X-ray examination (a = 546.2, c= 1259.1 pm, space group D^-14/mmm) shows that the octahedral distortion of the [Cu304Cl2] 4 ~-network cannot be explained only by the JAHN-TELLER effect.

 Title     
 Abstract    Upon use of a synthetic method reported earlier by us respective alloys of Na/Sn, Na/Ge and Na/Sb are dissolved in ethylene-diamine and the title compounds precipitated from the solutions in high yield. By recrystal-lisation well shaped, stable crystals are obtain-ed. The crystal structure of [Na4 • 7 en]Sn9 confirms the presence of a Sn9 4 ~-polyhedron which had been suggested by us on the basis of other investigations. The Sn9 4_ -polyhedron may be described as a distorted tricapped trigonal prism. Ethylenediamine is coordi-nated to Na+-ions exclusively.

 Title    Über Oxocuprate, XVI Ba9Cu7015Cl2 mit Cu 2+ in neuer Koordination About Oxocuprates, XVI Ba9Cu7015Cl2 with Cu 2+ in a New Coordination  
 Abstract    Single crystals of BagC^OisC^ were prepared and investigated by X-ray diffraction methods. They crystallize with hexagonal symmetry (a =1125.7; c = 585.3 pm, Space group D|h-P6/mmm). Cu 2 + has the well-known square 0 2--coordination. The squares are connected to rings of 6-fold symmetry. Another Cu 2+ has a so for unknown coordination of 12 0 2 ~-neighbours. The differences in respect of other oxohalogenocuprates are discussed.

 Abstract    The new ternary compounds NaAlSe2, NaAlTe2, NaGaTe2 and KAlTe2 crystallize in the Tl I Tl III Se2-structure type. The analogous Tl-compounds build up the same structure but show a variable composition within the limits (NaJTli_a.)TlSe2 (Oca; <0.47) and (Ka.Tli_jr)TlSe2 (0 <x <0.56). The compounds KAlSe2, KGaSe2, KInSe2 and KGaTe2 crystallize in a new structure type.

 Title    Fluorreiche Oxofluorovanadate(V): Die Kristallstruktur von [enH2] [VOF5]  
 Abstract    The crystal structure of triclinic [enH2][VOF5], prepared in aqueous solution, has been determined from X-ray diffractometer data (i? = 0.076 for 527 reflections). The structure contains monomeric [VOFs] 2--ions. The bond distances are 1.54(1) Ä (terminal oxygen), 1.80(1) (average for the cis-fluorine atoms) and 2.10(1) Ä for the fluorine atom in trans-position to the terminal oxygen atom. This fluorine atom is involved in strong hydrogen bonds originating from the [NHaCH^CH^NEy 2 " 1 -cation with cisoid conformation. Earlier results about the existence of K2VOF5 could not be confirmed.

 Title    Röntgenographische Strukturuntersuchung von Cäsiumhexaoxo-tetrahydroxo-pentaborat-2-dimethylsulfoxid X-ray Study of the Structure of Cesiumhexaoxo-tetrahydroxo-pentaborate-2-dimethyl Sulfoxide  
 Abstract    The compound Cs[Bs0 6 (OH)4 ] • 2 DMSO was prepared by hydrolysis of tris(methoxy)-borane in organic solvents with small amounts of water in presence of cesium ierf-butylate and recrystallized in DMSO (dimethyl sulfoxide). Cs[Bs0 6 (0 H)4 ] • 2 DMSO crystallizes in the monoclinic space group P2i/a with a = 9.593(2), 6 = 19.179(4), c = 11.585(2) Ä, ß = 119.99(2)° and Z — 4. The crystal structure was determined by single-crystal diffracto­ meter data and refined to a conventional R value of 9.9%. The crystal structure consists of chains of pentaborate anions [Bs0 6 (OH)4 ]-linked by hydrogen bonds. The cesium cation and the DMSO molecules join the chains to sheets by coordination and hydrogen bonds respectively.

 Abstract    G e r h a r d C o r d i e r u n d H e r b e r t S c h ä f e r BaMnSb2, SrMnBi2 and BaMnBi2 have been prepared and structurally characterized. The new compounds are isotypic and crystallize tetragonal in the SrZnBi2 structure with the following constants: BaMnSb2: a = 4.53 ± 0.01 A, c = 24.34 ± 0.03 A, c/a = 5.37. SrMnBi2: a = 4.58 ± 0.01 A , c = 23.13 ± 0.03 A, c/a = 5.05. BaMnBi2: a — 4.63 ± 0.02 A, c = 24.22 i 0.05 A, c/a = 5.23. The transition metal atoms form together with the semimetal atoms sheets of tetragonal pyramids separated by double layers of alkali earth atoms. In these double layers there are inserted Bi/Sb-square nets.

 Title    Ein Beitrag zur Kristallchemie dreiwertiger Seltenerdoxide Zur Stabilisierung der m onoklinen B-Form  
 Abstract    Single crystals of 1 — a'Ho203 : xCaO (x = 0.07), CaHoC>2.5 (A) and Cao.5H 01.5O2.75 (B) were prepared by high temperature reaction and investigated with X-ray single crystal data. It can be shown that small amounts of CaO stabilize the monoclinic B-Typ of rare earth oxides. Phase (A) and (B) cannot be seen as a stabilized B-type crystal because they have an new crystal structure with space group C.7h-P 2 i/m, a = 656.6, b = 356.7, c = 529.4pm , ß = 92.3°; a = 650.2, b = 352.4, c = 584.5, ß = 92.3°.

 Abstract    1,2 A 3 ,3 A 3 -Azadiphosphiridines are avaüable by elimination of hydrogenhalide from ß-and y-functional molecular frameworks and by 1 + 2 cycloaddition of phosphinidenes towards aminoiminophosphanes. In contrast to other three-membered phosphorus com-pounds, azadiphosphiridines decompose by 2 +1 cycloreversion to aminoiminophosphanes and phosphinidenes. The molecular structure of an azadiphosphiridine demonstrates the trans arrangement of the exocyclic ligands and the planarity of the endocyclic nitrogen.

 Abstract    Single crystals of the stable modification of selenium tetrachloride (a-SeCU) were grown by sublimation, and the crystal structure was determined. As that of metastable ß-SeCU it contains tetrameric cubane-like molecules Se4Cli6, but with different point symmetry and in positions which correspond to those of the atoms of the tungsten structure type.

 Title    Die Struktur des Na7Ga13-I und ein Konzept zur bindungsmäßigen Deutung The Structure of NavGai3-I and its Characterization by a Bonding Scheme  
 Abstract    The new compound NayGa^-I crystallizes in the trigonal-rhombohedral system, space group R 3 m, with the constants a = 1496.5(3) pm, c = 3893(1) pm, c/o = 2.60. The Ga atoms form Gai2 icosahedra and Gais clusters, connected to a threedimensional net. The arrangement of these clusters is related to the MgCu2 structure. The Na content of this compound correlates with the number of electrons necessary for a stable electron configuration in the Ga partial structure. The BaAl4 type structure of NaGa4 has been confirmed by single crystal data.

 Title    Phasenbeziehungen im System As2Te3—Asl3 und die Kristallstruktur von As5Te7I Phase Relations in the System As2Te3-Asl3 and the Crystal Structure of AssTe7l  
 Abstract    The system As2Te3-Asl3 is quasibinary and includes the intermediate phases AssTe7l and a-AsTel with incongruent melting behaviour. The crystal structure of AssTe7l contains ribbons of condensed octahedral chains sharing common edges. Arsenic atoms are situated in the centres of the octahedra and -in a trigonal-pyramidal arrangement -at the borders of the ribbons. There are close relationships between the crystal structures of As2Te3 and AssTe7l as well as As5Te7I and a-AsTel. The particular expansion of the AsöTe7l one-phase region within the quasibinary system is discussed with respect to these structural relations.

 Title    Cyclisierungsreaktionen lithiierter Fluorsilanole und Aminofluorsiloxane - Kreuzdimerisierung eines Silicenium-Ylids Cyclisation Reactions of Lithiated Fluorosilanols and Aminofluorosiloxanes - Cross-dimerisation of a Silicenium-Ylid  
 Abstract    KOH reacts with bis(isopropyl-trimethylsilyl)-amino-difluorosilane to give the fluoro-silanol 1. An aminofluorosiloxane 2 is obtained in the reaction of [(Me3Si)2N]2SiF2 with KOH via a 1,3-silyl-group migration. The four-membered SiOSiN ring 5 can be prepared in several steps from 1. Six-membered SiO rings 8-10 are formed in the reaction of 1,3-fluorosilanols 6 and 7 with butyllithium. Lithiated 2 reacts with PCI3 to give a four-membered P2N2 ring 11, and with 2-methyl-2-propenal to give two isomeric (2 + 4) cycloadducts 12 and 13. The silicenium ylid formed initially by thermal elimation of LiF from lithiated 2 in PE/THF cross-dimerises to give a Si2N2 ring 14. If the reaction is carried out in n-heptane, the product after recrystallisation from acetone, 16, is an isomer of 14. The crystal structures of 14 and 16 have been determined.

 Abstract    PPh 4 [VOBr4] was prepared by the reaction of PPh4Br with VOBr3 in CH2Br2 solu-tion. The structure of the dark violet crystals was determined with X-ray diffraction. PPli4[VOBr4] crystallizes in the space group P4/n with the lattice constants a = 1275.9 and c = 784.5 pm with two formula units per unit cell. The structure type corresponds to the frequently encountered AsPh4[RuNCl4] type. The VOBr4~ ion forms a square pyramid; the V = O bond has a length of 155 pm. In the IR spectrum, the V —O stretching vibration appears at 922 cm -1 .
