 Title    Structural Study of a Binuclear Zinc Complex of 2,6-Diacetylpyridine Bis{N(4)-dimethylthiosemicarbazone}, [Zn(2,6Ac4DM)]2 * MeCN  
 Abstract    Zinc, 2,6-Diacetylpyridine Bis{N(4)-dimethylthiosemicarbazone}, Electrochemical Synthesis Zinc metal was oxidized in the presence of 2,6-diacetylpyridine bis{N(4)-dimethylthiosemi-carbazone} (2 ,6 H2Ac4DM) in an acetonitrile solution, to produce a complex of the formula [Zn(2 ,6 Ac4 DM)]2-CH3CN. One of the zinc atoms is distorted octahedrally 6-coordinate and the coordination involves both pyridyl nitrogen atoms of the two ligands, the imine nitrogen atom and the thiolato sulfur atom of one thiosemicarbazone moiety of each ligand. The other zinc center is distorted tetrahedrally 4-coordinate with NS coordination of the two remaining thiosemicarbazone moieties. The complex crystallizes in the monoclinic space group C2/c with a = 14.952(2), b = 17.656(3), c = 15.553(4) A, ß = 111.456(16)°, V= 3821.5(13) A andZ = 4.

 Title    Synthesis, Spectroscopic Characterization and Crystal and Molecular Structures of {Ph4 P[(Se0 4 )(SnPh3 )(SnPh3X)]}n (X = Cl, Br)  
 Abstract    The reactions of bis[triphenyltin(IV)] selenate monohydrate [(Ph3Sn)204S e H 2 0 ] with tetraphenylphosphonium halides PluPX (X = Cl, Br) led to the formation of 1:1 complexes of formula {Ph4P[(Se0 4)(SnPh0 (SnPh3X)]k [X = Br (I) or Cl (II)], which were characterized by infrared, Mössbauer and H, 13C and Sn NMR techniques and by X-ray diffractometry. The complexes have polymeric structures in which the [SnPh3]+ units alternate with bridging [SeC>4]2-units, each of which also bears an SnPh3X side chain. In both the [SnPh3]+ and the [SnPhsX] units the coordination polyhedron of the tin atom is a distorted trigonal bipyramid.

 Title    New Magnesium Compounds /fcE2Cu2Mg (RE = Y, La -Nd, Sm, Gd -Tm, Lu) with Mo2FeB2 Type Structure  
 Abstract    The title compounds were synthesized by reaction of the elements in sealed tantalum tubes in a water-cooled sample chamber in a high-frequency furnace. These magnesium intermetallics crystallize with the tetragonal Mo2FeB2 type structure, space group PMmbm. The lattice pa­ rameters of all compounds were refined from X-ray powder data. Single crystal X-ray data yielded a = 792.09(6), c = 396.31(8) pm, wR2 = 0.0396, 315 F 2 values for La2Cu2Mg, a = 778.30(5), c = 384.04(5) pm, wR2 = 0.0954, 214 F 2 values for Nd2Cu2Mg, and a = 762.65(5), c = 374.09(3) pm, wR2 = 0.0566, 186 F 2 values for Y2Cu2Mg with 12 variable parameters for each refinement. The /?£, 2Cu2Mg structures can be described as an intergrowth of distorted A1B2 and CsCl related slabs of compositions RECui and REMg. Chemical bonding in La2Cu2Mg was investigated on the basis of extended Hückel calculations and compared to isotypic La2Cu2ln. This structure was also refined from single crystal X-ray data: PMmbm, a = 780.8(2), c = 400.1(2) pm, wR2 = 0.0351, 211 F 2 values and 12 variable parameters.

 Title    A New Binuclear Lutetium(III) Dimethyl-N-trichloroacetylamidophosphate Complex with a 7 , 7 *-Dipyridyl Bridge, {Lu[CCl3C(0)N P(0)(0C H 3)2]3}2-A x(7,7'-dipy)  
 Abstract    A new type of binuclear coordination compound of lutetium, {Lu2L6 /i-(7 ,7 '-dipy)} (where L = dimethyl-N-trichloroacetylamidophosphate anion and 7 ,7 '-dipy = 4,4'-dipyridyl), has been obtained. The IR spectroscopic data reveal that the ambidentate phosphoryl ligand is coordinated to the metal center in a bidentate manner via the phosphoryl and carbonyl oxygen atoms. The crystal and molecular structure of {LniLö-^-(7 ,7 '-dipy)} has been determined by means of X-ray diffraction (triclinic, space group P i with parameters: a = 9.259(2), b = 12.530(3), c = 16.548(3) A, a = 85.44(3)°, ß = 75.64(3)°, 7 = 70.56(3)°, Z = 1). The structure is made up of centrosymmetric binuclear molecules, in which the neutral heterocyclic ligand is coordinated to the metal centers in a bidentate bridging manner via its nitrogen atoms. The coordination number of each Lu(III) atom is 7 [60(L~) + N((7 ,7 '-dipy)]. Phosphoryl and carbonyl groups of the L~ ligands are disposed in syn-position and are included in the six-membered chelate metallocycles. The coordination polyhedron of lutetium can be described as distorted mono-capped octahedron.

 Abstract    Imidovanadium(V) Trichlorides The reactions of Me3SiN=VCl3 (1) with MeOH, PhOH, HCl, PyH+Cl~ or LiO'Bu have been studied. The reductive decomposition of 1 by hydrogen chloride in toluene yields HN=VC13 as a labile intermediate which could be isolated only in a small amount. The syntheses of RN=VC13 (R = neopent, "Pr, cyclohex, CPh3, 1-Ad) and [('BuN)2V2Cl4(/i-OC13H9)2] (15) are also described. All compounds obtained are characterized by 5 V NMR spectroscopy, the fluorenolato complex 15 by X-ray diffraction analysis.

 Title    Oxovanadium(IV), Nickel(II) and Palladium(II) Complexes of Tridentate Salicylaldiminates Derived from 2,4-Di-terMmtyl-6-aminophenol  
 Abstract    Several new binuclear nickel(II), oxovanadium(IV) and palladium(II) complexes (MLX) of tridentate salicylaldimines (LX H2) obtained from substituted salicylaldehydes and 2,4-di-tert-butyl-6-aminophenol, as well as mononuclear nickel(II) and oxovanadium(IV), MQx nH20, complexes with hydrogenated LX H2 ligands (QXH2) have been prepared and their spectroscopic, magnetic and catalytic activity (for PdLx) have been investigated. NiLx and VOLx complexes when dissolved in pyridine, take up three or two pyridine molecules to form six coordinated complexes, respectively. The Ni(II) and VO(IV) complexes obtained from QXH2 can be formu­ lated as NiQx-3H20 and VOQx H2O. All VO(IV) complexes have been characterized by ESR parameters. It has been found that some PdLx complexes without any preliminary activation, in EtOH, THF and DMF exhibit high catalytic activity in the hydrogenation of nitrobenzene or cyclohexene at room temperature and at 30 -40 °C under 760 torr H2. When this reaction has been carried out in the ESR cavity at room temperature the triplet of 12 line multiplets due to the nitroxyl type coordinated radical (g = 2.013, AN = 10 G, A = 0.8 G) was detected.

The Pentaiodide-Ion I5~; an Overview: Preparation and Crystal Structure of [Rb(C16H240 6)](I5) H 20  
 Abstract    Crown Ether, Pentaiodide, Polyiodides [Rb(benzo-18-crown-6)](I5) H20 could be prepared by the reaction of benzo-18-crown-6, rubidium iodide, and iodine in ethanol / dichloromethane. It crystallizes in the monoclinic space group P2j/a with a = 1881.8(3), b = 1439.0(2), c = 2269.0(3) pm, ß = 111.24(1)° and Z = 8. The crystal structure was refined to Rv = 0.038 for 5310 reflections. It contains two independent molecules. The two cations and the coordinating water molecules form a zigzag chain running along [100] paralleled by two structurally similar pentaiodide chains with one leg of the V-shaped pentaiodide ion forming the backbone of the chain. In both cases the other leg stands out in a novel fashion without forming a coplanar cis or trans configuration known from other pentaiodides. Anionic motifs of other crystalline pentaiodides are summarized and discussed. E in leitu n g

 Title    Kinetics of the Substitution of Norbornadiene in Tetracarbonyl(norbomadiene)molybdenum(0) by 2,2'-Bipyridine  
 Abstract    The kinetics of the thermal substitution of norbornadiene (nbd) by 2,2'-bipyridine (2,2'-bipy) in (CO)4Mo(CyH9) was studied by quantitative FT-IR and UV-VIS spectroscopy. The reaction rate exhibits first-order dependence on the concentration of the starting complex, and the observed rate constant depends on the concentration of both leaving nbd and entering 2,2'-bipy ligand. The mechanism was found to be consistent with the previously proposed one, where the rate determining step is the cleavage of one of the two Mo-olefin bonds. The reaction was performed at four different temperatures (35 -50 °C) and the evaluation of the kinetic data gives the activation parameters which now support states.

 Title    Chemischer Transport intermetallischer Phasen IV: Das System Fe -Ge Chemical Vapour Transport of Intermetallic Phases IV: The System Fe -Ge O  
 Abstract    Chemical Vapour Transport, Phase Diagram Six phases exist in the binary system iron-germanium Fe3Ge, ß, r7, Fe6Ge5, FeGe and FeGe2. All phases could be prepared by chemical transport with iodine as transport agent in the temperature range between T x (600 °C) and T2 (950 °C). Two phase diagrams have been known in the literature from specific experiments of chemical vapour transport. It is now possible to decide which phase diagram is the most valid description.

 Title    A Simple High-Yield Synthesis of Gallium(I) Tetrachlorogallate(III) and the Reaction of Digallium Tetrachloride Tetrahydrofuran Solvate with 1,2-Diols  
 Abstract    Gallium(I) tetrachlorogallate(III) Ga[GaCU] was prepared in quantitative yield by thermal de­ composition of dichlorogallane [HGaChk, which is readily available from EtsSiH and [GaCl3]2. The reaction of catechol with solutions of this gallium(I) tetrachlorogallate(III) in tetrahydro­ furan leads to the evolution o f hydrogen gas and affords a dinuclear gallium(III) complex with penta-coordinate metal atoms chelated and bridged by mono-deprotonated catechol ligands. In the crystalline phase tetrahydrofuran molecules are hydrogen-bonded to the hydroxy groups: [G a(l,2 -0 CöH4 0 H)Cl2(C4H8 0)]2. The reaction with pinacol also gives hydrogen and the anal­ ogous product [Ga(0 CMe2CMe2 0 H)Cl2(C4Hg0)]2. The structures of the two compounds have been determined by X-ray diffraction. A mechanism of the new reaction has been proposed which involves oxidative addition of the diol to the solvate (THF)Cl2Ga-GaCl2(THF) present in the tetrahydrofuran solution to give a gallium hydride intermediate.
