      Well-Defined Heterometallic and Unsymmetric M2O2 Complexes Arising from Binding and Activation of O2 (pages 179–187)

      Isaac Garcia-Bosch, Xavi Ribas and Miquel Costas

      Article first published online: 9 DEC 2011 | DOI: 10.1002/ejic.201100957

      Oxygen binding and activation at unsymmetric and heterometallic complexes by well-defined MO2M′ species is reviewed. Studies described so far have provided evidence for a rich chemistry. Novel spectroscopic properties, electronic structures and reactivities are emerging, and they suggest a myriad of fresh avenues still to be explored.

      Thumbnail image of graphical abstract

      The structure of (H3O)2B12F12·nH2O (n = 6) consists of a CCP array of B12F122– anions intercalated with nonplanar networks of O6 rings of H3O+ ions and H2O molecules. The n = 6 compound rapidly and reversibly desorbs water in discrete stages to form n = 4, 2, and 0 phases, which demonstrate latent porosity.

    6. Thermal Decomposition of POMs

      Thermal Decomposition of Ammonium Paratungstate Tetrahydrate Traced by In Situ UV/Vis Diffuse Reflectance Spectroscopy (pages 213–216)

      Martin J. G. Fait and Hans-Joachim Lunk

      Article first published online: 8 DEC 2011 | DOI: 10.1002/ejic.201100838

      Thumbnail image of graphical abstract

      The graphic illustrates the stepwise increasing number of nearest tungsten ions due to thermally induced condensation of WO6 octahedra, which was calculated from the edge energies of the ligand-to-metal charge transfer transitions of tungsten ions. These optical transitions, in turn, were determined from the in situ UV/Vis diffuse reflectance spectra while heating in oxidative and reductive atmospheres.

      Yuji Mikata, Kyoko Takahashi, Yuka Noguchi, Masami Naemura, Anna Ugai, Saori Itami, Keiko Yasuda, Satoshi Tamotsu, Takashi Matsuo and Tim Storr

      Article first published online: 7 DEC 2011 | DOI: 10.1002/ejic.201100953

      Thumbnail image of graphical abstract

      Twelve [ReIL(CO)3]n+ (L = carbohydrate-pendant ligand; n = 1 or 0) complexes have been prepared. All complexes were incorporated into HeLa S3 cells. With respect to the corresponding ReI complexes without the pendant carbohydrate functions, N-(2-pyridylmethyl)glycine complexes exhibited carbohydrate enhanced cellular uptake. The complexes stay in the cytosol and cannot penetrate into nucleus.

      Thumbnail image of graphical abstract

      Titania–alumina nanocomposites were synthesized by an aqueous sol–gel route starting from titanyl sulfate. The titania–alumina composition containing 5 mol-% Al2O3 (TA-5), annealed at 700 °C, shows the highest photocatalytic activity. Nanocoatings developed over glazed ceramic surfaces indicated preferentially hydrophobic character.

      A series of π-extended tetrathiafulvalene (TTF) Schiff base ligands has been prepared. Four complexes have been prepared with these redox active ligands, and the electrochemical and spectroscopic behavior of these compounds have been studied. These new imine-bridged TTF ligands with diverse substitution patterns are useful for the syntheses and design of new metal complexes.

      Thumbnail image of graphical abstract

      Supported titanium and vanadium oxide catalysts have been synthesised by atomic layer deposition. The influence of the support type (mesoporous silica vs. mesoporous phenolic resin) on the catalytic activity has been investigated. The support–oxygen–metal bond is assumed to be critical for catalytic behaviour.

    6. Key–Lock Principle

      The N,N-Bis(terphenyl)aminophosphenium Cation – A Sensitive Probe for Interactions with Different Anions (pages 261–271)

      Fabian Reiß, Axel Schulz and Alexander Villinger

      Article first published online: 8 DEC 2011 | DOI: 10.1002/ejic.201100978

      Jeng-Horng Sheu and Ming-Der Su

      Article first published online: 12 DEC 2011 | DOI: 10.1002/ejic.201100939

      Thumbnail image of graphical abstract

      DFT results suggest that the thermolysis of heavy 1,3-butadienes with sterically overcrowded substituents can lead to two kinds of intramolecular reactions: cycloaddition and 1,2-migration. Our findings indicate that the heavier the group 14 atoms that participate in the intermediate carbene species, the more kinetically stable its intramolecular products.

    8. Thiolate/Thioether Complexes

      Platinum(II) Complexes Bearing a Thiolate/Thioether Ligand – Hemilability vs. Dealkylation (pages 282–291)

      The thiolate/thioether ligand 4-methylthio-2-thioxo-1,3-dithiole-5-thiolate coordinates to a diphosphane platinum(II) centre by a firm metal–thiolate link and an incipient metal–thioether link. The dative interaction leads to the displacement of a phosphane ligand (hemilabile behaviour) or to the activation of the C–SMe bond on the platinum centre to generate a dithiolene complex.

      Thumbnail image of graphical abstract

      A series of zinc complexes that contain phenolate phosphane ligands has been prepared. The formation of lithium zincate Zn[LtBuLi(THF)]2 instead of Zn2(LtBu)2(THF) by salt metathesis highlights the significance of the synthetic strategy in the complex preparation.

      The generation of the [FeFe]-hydrogenase model complexes [Fe2(CO)6{μ-SCH(C6H5)C6H4S-μ}] (3b) and [Fe2(CO)6{μ-SCH(C6H4)–S–C6H3S-μ}] (4b) is reported. A plausible mechanism for the formation of 3b is described, in which thiobenzophenone (2a) acts as a sulfur transferreagent, while the ortho-metallated complex [Fe2(CO)6{μ,κ,S,SCH(C6H5)C6H42}] (3a) is the reaction pathway intermediate.

    13. Chemosensors

      A Highly Selective Fluorescent and Colorimetric Chemosensor for ZnII and Its Application in Cell Imaging (pages 327–332)

      Guoqiang Xie, Yanjun Shi, Fengping Hou, Hongyan Liu, Liang Huang, Pinxian Xi, Fengjuan Chen and Zhengzhi Zeng

      Article first published online: 8 DEC 2011 | DOI: 10.1002/ejic.201100804

      Thumbnail image of graphical abstract

      A fluorescent, colorimetric chemosensor, L1, based on 8-aminoquinoline, has been developed as a sensor for Zn2+. L1 exhibited high selectivity and sensitivity towards Zn2+ over other common metal ions in a physiological pH window with a 1:1 binding mode. Fluorescent imaging of Zn2+ in living cells has been successfully demonstrated.
