    Abstract [en]

    By slow evaporation of solutions containing UO2(ClO4)(2) and an excess of HClO4, single crystals of [UO2(ClO4)(2)(H2O)(3)] (1) and [UO2(H2O)(5)](ClO4)(2) (2) were obtained and their structures were determined. From similar solutions prepared from stoichiometric amounts of UO3 and perchloric acid, crystals of [UO2(H2O)(5)](ClO4)(2)(.)2H(2)O (3) were obtained. The trihydrate (monoclinic, P2(1)/c, a=545.44(1) pm, b=1811.09(5) pm, c = 1032.46(2) pm, beta=90.016(1)degrees)consists of uranyl ions, which are coordinated by two monodentate perchlorate ions and three water molecules. The pentahydrate (monoclinic, P2(1)/n, a=529.35(2) pm, b=1645.43(6) pm, c = 1480.18(6) pm, beta=99.847(1)degrees)contains uranyl ions coordinated by five water molecules. The same structural unit can be found in the heptahydrate, whose structure was re-determined (orthorhombic, Pbcn, a=920.9(3) pm, b=1067.9(3) pm, c=1445.7(3) pm). In this structure, two molecules of water of crystallization are present.

    Abstract [en]

    By slow evaporation of solutions containing Ln(ClO4)(3) (Ln = Pr, Nd, Sm), H5IO6 and an excess of HCIO4, crystals of the title compounds could be obtained. Their structures were determined by single-crystal X-ray diffraction. The compounds crystallize in the monoclinic crystal system, space group I2/a. They contain two types of periodate ions: octahedral H4IO6 groups and two crystallographically different I2O10 groups. which consist of two edge-sharing octahedra. These anions coordinate to the canons as bridging groups yielding a three-dimensional network. Together with some water of crystallization, a coordination number of 9 is achieved around the lanthanide ions with a tri-capped trigonal prismatic geometry.

    Abstract [en]

    The reaction of palladium(H) bromide or palladium(II) iodide with the respective gallium(III) halogenide in the presence of aromatic solvents leads to the formation of palladium(II) tetrabromo- and tetraiodogallate. The compounds are isostructural {monoclinic, C2/m, Pd[GaBr4](2): a=1267(2), b=808(1), c=722(1) pm, beta=94.5(1)degrees; Pd[GaI4](2): a=1363(1), b=849.9(4), c=756.6(7) pm, beta=95.38(3)degrees}. The structures contain mononuclear complexes Pd[GaX4](2), where X- = Br- (1), I- (2). The crystal structures of 1 and 2 were determined by single-crystal X-ray diffraction. Crystals of both compounds turned out to be similarly twinned.

    Abstract [en]

    The reactions of platinum(II) iodide with triethyl- or trimethylsulfonium iodide in acetonitrile solution lead to the formation of crystalline products (Et3S)(2)[PtI6] (1) and [Me3S]=[PtI6]center dot CH3CN (2), respectively. The formation of Pt(IV) complexes may be explained either by disproportionation of PtI2 or oxidation by oxygen. Palladium(II) iodide reacts with triethylsulfonium iodide to give the palladium(II) complex (Et3S)(2)[PdI4] (3). The crystal structures of 1-3 were determined by single-crystal X-ray diffraction. In the crystal structures, the compounds 2 and 3 exhibit an extensive hydrogen-bonding network.

    Nobel-Metal Centered Polycations Au@Bi-10 (5+) or Pd@Bi-10 (4+) Embedded in Halogenido-Bismuthate(III)-Stannate(II) Frameworks2009Ingår i: Zeitschrift für Anorganische und Allgemeines Chemie, ISSN 0044-2313, E-ISSN 1521-3749, Vol. 635, nr 4-5, s. 743-752Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The metal-rich halogenides AuBi14 delta Sn2+delta X21-delta (delta approximate to 0.4) and PdBi15 delta Sn2+delta X21-delta (delta approximate to 0.6) with X = Cl. Br were crystallized from melts of the metals and BiX3. In the rhombohedral structures (space group R (3) over bar: a approximate to 1050 pm: alpha approximate to 94 degrees), noble-metal centered pentagonal antiprisms [Au@Bi-19](5+) resp. [Pd@Bi-19](4+) are embedded in halogenidometallate frameworks (3)(x)[Bi-4 delta Sn2+delta X21-delta](5) resp. (3)[Bi-4 delta Sn2+delta X21-delta](4). Mixed Bi-III/Sn-II site occupation allows the framework to adopt different charges. Further exchange of (BiX3)-X-III against (SnX2)-X-II results in vacancies (delta) on the position of an isolated halide ion. In quantum chemical calculations the naked metal-clusters are found to be stable in D-5d symmetry with interatomic distances close to the observed ones. The significance of interactions between the Wade-type host cluster Bi-10(4+) and the closed-subshell guest atoms Au+ or Pd-0 is reflected in the molecular orbital diagram, the population analyses and the ELI-D.

    The metal-rich compounds (1)(infinity)[PdBi6][(Bi,Sn)(1-delta)Br5-delta,] with delta(1) = 2/13, delta(1)' = 5/26, or delta(2) = delta(2)' = 2/12 were synthesized from Bi2Pd, BiBr3, and Sn at 300 degrees C. The crystal structures contain intermetallic rods (1)(infinity)[Pd@Bi2/1Bi8/2](2.5+) embedded in salt-like matrices, which consist of groups of bromido-bismuthate(III)-stannate(II) octahedra [(Bi,Sn)(n)Br4n+2](m-) (n = 2, 3) and isolated Br- ions. Metrical incompatibilities of the two subsystems in the crystalline metal-salt hybrid result in non-stoichiometry of the salt pan associated with complex superstructures. The average structure is described in the orthorhombic space group Pmmm with a approximate to 408 pm, b approximate to 2263 pm, c approximate to 849 pm. It feigns statistical distribution of vacancies and orientational disorder of the concatenated octahedra. By choosing the modulation vectors q(i) = 2/ta* + 1/2b* + 1/2c* with t(1) = 13 or t(2) = 12, the additional weak reflections of the diffraction patterns are indexed. Ordered structure models are achieved in the [3+1]-dimensional superspace group Pmmm(alpha 1/21/2)000. Metallic conductivity along [100], i.e. the direction of the (1)(infinity)[Pd@Bi2/1Bi8/2](2.5+) rods, was determined for a single-crystal. One-dimensional band structure calculations reveal Bi p-bands crossing the Fermi level for formula charges higher than 2+. The electron localization indicator (ELI) indicates two-center Bi-Bi bonds as well as multi-center bonds inside the metallic part, whereas the bismuth l one-pairs point towards the non-conducting part of the structure.
