 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.

 Abstract    Crystal structure analysis of (C O)5CrPH2COOH (a = 1338.2, b = 622.6, c = 1161.5 pm, ß = 96,77°, P 2 1/c, Z = 4, R -0.0330) has shown the complex to be dimerized via hydrogen-bonds of the COOH group. Geom etrical parameters of the hypothetical free ligand [H2PCO O H ]2 were calculated using the HF/3-21 G*, HF/6-31G** and MP2-FU/6-31 G** basis sets. Bond lengths and bond angles o f the calculated free ligand are similar to those derived from the crystal structure analysis of the coordinated ligand and are not significantly influenced by coordination and/or intermolecular interactions.

 Abstract    Single crystals of (Cu,Zn)3 75Mo30 12 have been prepared by crystallization from melts and investigated by X-ray diffractometer techniques. (Cu,Zn)3 75Mo3Oi2 crystallizes orthorhom-bically, space group D^-P212,21, Z = 4, a = 17.947(9), b = 5.092(3), c = 10.685(5) A. It is isotypic to Cu385Mo30 12. All molybdenum atoms are tetrahedrally coordinated by oxygen atoms. There are layers of C u 0 6 and Z n 0 6 octahedra, while other metal sites are occupied by copper in a deformed prismatic coordination with one oxygen atom at a remarkably greater distance from copper than the other five. Some of the zinc atoms occupy positions in chains of face-sharing octahedra with an occupancy factor of 0.75. The crystal structure is discussed with respect to the isotypic compound Cu385Mo30 12 and compounds of the type CuLnMo20 8.

 Title    Zum Ligandeinfluß in neuen Ni(0)-Komplexen disubstituierter Butadiine On the Influence of Ligands in New Ni(0) Complexes of D isubstituted Butadiynes  
 Abstract    It has been shown that disubstituted butadiynes react with L2Ni(C2H 4) to yield m ono­ nuclear complexes L2Ni(?/2(l:2)-R C = C -C = C R) (L = o-T ol-0)3P, R = SiMe3 (1), 'Bu (2), Ph (3)). For the first time, the crystal structure of a nickel(O) alkyne complex carrying phosphite ligands (2) has been determined. The reaction of (dipy)Ni(cod) (L2 = dipy) with butadiynes R 'C = C -C = C R is strongly influenced by the substituents of the butadiyne. With R' = R = SiMe3 (4), 'Bu (5) and Ph (6) or R' = Ph, R = SiMe3 (7) and R ' = 'Bu, R = SiMe3 (8) mononuclear complexes (dipy)Ni(?72(l:2)-R 'C = C -C = C R) have been observed. Depending on the stoichiometry with R = R ' = Ph (9) and 'Bu (10) dinuclear complexes |(dipy)Ni}2(/<-?72(l:2),?72(3 :4)-R 'C = C -C = C R) having two Ni atoms coordinated to two C = C triple bonds were obtained. By contrast, with R ' = R = SiMe3 (11), R' = 'Bu, R = SiMe3 (12) and R' = Ph, R = SiMe3 (13) the two Ni-centers were found to coordinate to the same C = C triple bond to yield another type of a dinuclear complex {(dipy)Ni}2(w-?72(l:2),//2(l:2)-R 'C = C -C = C R). Com pound 5 has been characterized by X-ray crystal structure analysis. The structures of 2 and 5 are com pared to that of the well-known complex (Ph3P)2Ni(?72(l:2)-'B u C = C -C = C 'B u) [1] to study the influence of different ligands L on the structural details. In comparison to the alkyne complexes L2Ni(//2-R C = C R) in butadiyne complexes of the L2Ni(//2(l:2)-R 'C = C -C = C R) type there is only a slight effect of the different ligands. The uncomplexed C = C triple bond as a part of the second substi­ tuent in conjugation to the complexed C = C triple bond appears to level out the influence of ligands and substituents.

 Title    C a M g 2N 2 -ein gemischtes Erdalkalimetallnitrid mit fl#if/-La20 3-Struktur CaMg2N 2 -a Mixed Alkaline-Earth Metal Nitride with anti-La20 3 Structure  
 Abstract    CaMg2N 2 (trigonal, P 3 m l (Nr. 164); a = 354.046(1), c = 609.079(2) pm; Z = 1) is isotypic to the anti-La20 3 structure with octahedral and tetrahedral coordination for Ca2+ and M g2+ ions, respectively. The compound has been prepared by the reaction o f the binary nitrides Ca3N 2 and M g3N 2 (molar ratio 1:2) in a tungsten crucible under a pure nitrogen atmosphere at 1050 °C. The formation o f the solid CaM g2N 2 may be interpreted in analogy to reactions o f related oxides as an acid-base reaction between the binary nitrides with different coordina­ tion tendencies o f Ca2+ and M g2+ ions. A n analysis o f the binary aristotype anti-La20 3 indica­ tes that this structure is predisposed for building ternary phases.

 Abstract    Bis(fluorodiisopropylsiiyi)amine [(Me2H C)2SiF]2NH (1) reacts with the disodium salt of catechole or the disodium salt of resorcinol in a molar ratio 1:1 to give the seven-membered heteraphane [HN(Me2H C)2SiO]2C6H4 (2) resp. the 16-membered heteraphane [HN(Me2H C)2SiOC6H4O Si(CHM e2)2]2 (3). The chain-like compound [(Me2H C)2SiFNHSi(CHMe2)20 ] 2C6H4 (4) is obtained by the reaction of 1 with disodium resor-cinolate. Ergebnisse und Diskussion Läßt man Bis(fluordiisopropylsilyl)amin (1) im Molverhältnis 1; 1 mit dinatriiertem Brenzcatechin reagieren, entsteht das neuartige, siebengliedrige H eteraphan 2. Im Gegensatz zum Brenzcatechin sind bei Resorcin die Sauerstoffatome in 1,3-Stel-lung am A rom aten gebunden. Dies bewirkt, daß dinatriiertes Resorcin aus sterischen Gründen mit 1 nicht analog der Bildung von 2 zu einem acht-gliedrigen, sondern zum bislang unbekannten 16-gliedrigen H eteraphan 3 reagiert.

TTie compound crystallizes with ortho-rhombic symmetry, space group D'2 6 h-P n m a , a = 5.092(1), b = 10.624(3), c = 17.804(4) A, Z = 4 and is isotypic to NaCo2.3iMo30 12. The crystal structure is discussed and it is shown, that the trigonal prismatically coordinated copper positions are occupied in a different m an­ ner. One of the alternate sites is beside the centre of the prisms, and the other one is shifted towards one of the faces of the rectangular prism. This detail may be interpreted by assigning the valance states C u1 and Cu11. The M 0 6 octahedra are occupied statistically by copper and cobalt.

 Title    Zur Darstellung und Kristallstruktur eines neuen Kupfer-Antimon-Oxomolybdats: CuSbMo20 8 On the Synthesis and Crystal Structure of a New Copper Antimony Oxomolybdate: CuSbMo20 8  
 Abstract    Single crystals of the hitherto unknown com pound CuSbMo2O s were prepared by recrys­ tallization from melts in closed copper tubes and investigated by X-ray diffractometer techni­ que. CuSbMo^Os crystallizes in a new structure type with monoclinic symmetry, space group q ? h-I 1 2 /a l, a = 5.554(2), b = 4.916(1), c = 21.519(4) Ä, ß = 93.42(3)°, Z = 4. The crystal structure shows Sb111 in a one-sided coordination by four oxygen. Molybdenum shows the rare octahedral coordination by oxygen. M o 0 6 and C u 0 6 octahedra form triple layers stacked and connected by Sb ions along [001],

 Title    Darstellung und Kristallstruktur von [Cs4(Dibenzo-18-Krone-6)3](S6)2-2CH3CN Synthesis and Crystal Structure of [Cs4(Dibenzo-18-Krone-6)3](S6)2 * 2 CH3CN  
 Abstract    [Cs4(dibenzo-18-crown-6)3](S6)2-2CH3CN has been prepared from dibenzo-18-crown-6, Cs2C 0 3 and suifur in acetonitrile saturated with H 2S. The title compound crystallizes in space group P I (lattice dimensions: a = 10,507(7)Ä, b = 11,504(6) A, c = 17,792(9) A, a = 97,86(4)°, ß = 105,86(4)°, y = 101,48(5)°) with one formula unit. The crystallographic units are built of stacks of three crown ether molecules and two hexasulfide chains with the cations located between them. The conformation of the hexasulfide chains is all-cis.
