    1. Efficient Molybdenum Chelation

      From Siderophores and Self-Assembly to Luminescent Sensors: The Binding of Molybdenum by Catecholamides (pages 3689–3701)

      Molybdate reacts with 2,3-dihydroxybenzamide-containing ligands (catecholamides) to give stable orange-coloured cis-dioxido-MoVI complexes. This microreview discusses the role of such complexes in bacterial molybdenum uptake and highlights how their unique properties can be exploited in the self-assembly of supramolecular structures and the development of luminescent chemosensors for molybdate.

    1. Anion–π Interactions

      An Unusual Anion–π Interaction in an ;rido Organometallic Assembly: Synthesis, First Crystal Structure, and Computational Study (pages 3703–3707)

      Jamal Moussa, Vincent Gandon, Marie Noelle Rager, Max Malacria, Lise-Marie Chamoreau and Hani Amouri

      Article first published online: 14 JUL 2009 | DOI: 10.1002/ejic.200900497

      The organometallic assembly [Cp*Ir(η6-C6H2O4)(BF2)2(CF3SO3)][Cp*Ir(μ-Cl)3IrCp*] (3) was prepared and fully characterized. Remarkably, the X-ray molecular structure of 3 shows that an anion–π interaction occurs between the neutral component Cp*Ir(η6-C6H2O4)(BF2)2 of the assembly and the CF3SO3 anion. Computational analysis was carried out on 3 to unravel the nature of this noncovalent interaction.

      Aude Demessence, Adel Mesbah, Michel François, Guillaume Rogez and Pierre Rabu

      Article first published online: 24 JUL 2009 | DOI: 10.1002/ejic.200900329

      The structure of {Ni33-OH)2[(κ11)-(κ11)-μ4tdc]22-H2O)4}n (H2tdc = 2,5-thiophenedicarboxylic acid) has been solved by synchrotron powder X-ray diffraction. The polymer is built of [Ni1O6]2[Ni2O6] chains. It behaves as a metamagnet, bearing out the possible tuning of magnetic interaction by different π-electron ligands even at quite large distances.

    2. Polymorphic Lanthanum Hydroxide

      Controllable Synthesis and Luminescence Properties of La(OH)3 and La(OH)3:Tb3+ Nanocrystals with Multiform Morphologies (pages 3721–3726)

      Guang Jia, Yeju Huang, Yanhua Song, Mei Yang, Lihui Zhang and Hongpeng You

      Article first published online: 23 JUL 2009 | DOI: 10.1002/ejic.200900495

      Thumbnail image of graphical abstract

      One-dimensional La(OH)3 nanocrystals with multiform morphologies have been successfully synthesized by a facile hydrothermal process without using any surfactant, catalyst, or template. The morphologies of the products could be modulated by simply adjusting the pH values of the initial solution or by using different kinds of alkaline sources.

    3. N-Doped Ti Nanocatalysts

      Facile Synthesis of Anatase–Brookite Mixed-Phase N-Doped TiO2 Nanoparticles with High Visible-Light Photocatalytic Activity (pages 3727–3733)

      Li Li and Chun-yan Liu

      Article first published online: 21 JUL 2009 | DOI: 10.1002/ejic.200900369

      Thumbnail image of graphical abstract

      N-Doped anatase–brookite bicrystal TiO2 nanocatalysts were successfully designed and synthesized by a facile solvothermal route. Modification of TiO2 with N dopants narrowed the band gap and extendedthe absorption light from the UV region to the visible area. The mixing of anatase and brookite enhanced the quantum efficiency of the N-doped TiO2 samples.

    4. Spontaneous Reduction

      Spontaneous Reduction of High-Spin FeIII Complexes Supported by Benzoic Hydrazide Derivative Ligands (pages 3734–3741)

      Nouri Bouslimani, Nicolas Clément, Clément Toussaint, Sophie Hameury, Philippe Turek, Sylvie Choua, Samuel Dagorne, David Martel and Richard Welter

      Article first published online: 24 JUL 2009 | DOI: 10.1002/ejic.200900382

      Thumbnail image of graphical abstract

      Experimental evidence for the spontaneous reduction of new high-spin iron(III) FeIII(L(n))2Cl, L complexes to new high-spin iron(II) FeII(HL(n))2Cl2 mononuclear complexes was discovered. These processes were checked by EPR, cyclovoltammetric, and pseudo-steady voltammetric studies.

      Igor L. Fedushkin, Alexander S. Nikipelov, Alexandra A. Skatova, Olga V. Maslova, Anton N. Lukoyanov, Georgy K. Fukin and Anton V. Cherkasov

      Article first published online: 23 JUL 2009 | DOI: 10.1002/ejic.200900456

      Each metal unit of digallane (dpp-bian)Ga–Ga(dpp-bian) (5) may transfer two electrons to substrates, e.g. dibenzyl disulfides, without breaking the coordination of the dpp-bian ligand to the metal. In thecourse of the reaction of 5 with (Ph2CH2S)2, both ligand and metal are oxidized. Only the Ga center is oxidized when complex 5 reacts with one molar equivalent of tetramethylthiuram disulfide.

      Article first published online: 22 JUL 2009 | DOI: 10.1002/ejic.200900255

      Thumbnail image of graphical abstract

      Double perovskites of type Ca2Fe1+xW1–xO6 show degrees of antisite disordering that increase with the average oxidation stateof Fe. These compounds range from ascenario where the antiferromagnetic patches are isolated, to a model where the Fe-rich patches, which are strongly coupled via Fe–O–Fe superexchange interactions, present an excellent coherence across the crystal.

    7. Magnetic Manganese Compounds

      Inhomogeneous Magnet NaMnIII[BP2O7(OH)3]: Ferromagnetic Clusters Inserted in a Metamagnetic Matrix (pages 3758–3764)

      Tao Yang, Yan Zhang and Jianhua Lin

      Article first published online: 27 JUL 2009 | DOI: 10.1002/ejic.200900387

      Thumbnail image of graphical abstract

      Unlike the magnetic inhomogeneity in mixed-valent manganese perovskites, NaMnIII[BP2O7(OH)3] shows the valent singularity of manganese and is simultaneously an unusual inhomogeneous magnetic model, consisting of ferromagnetic clusters and a metamagnetic background.

    8. (Hydroxamato)tin(IV) Complexes

      Cyclic Trinuclear Diorganotin(IV) Complexes – The First Tin Compounds Bearing Oximehydroxamate Ligands: Synthesis, Structural Characterization and High In Vitro Cytotoxicity (pages 3765–3769)

      Thumbnail image of graphical abstract

      The first diorganotin(IV) complexes with a ligated oximehydroxamate were prepared and characterized by single-crystal X-ray diffraction, IR and multinuclear NMR spectroscopy and elemental analyses. They are cyclic trinuclear and the dibutyltin(IV) complex exhibits strong activity in vitro towards various human tumour cells.

      Three new hybrid materials for anionic surfactant removal from water have been prepared by the grafting of imidazolium,amine and pyridine moieties onto a MCM-41 mesoporous scaffold. The hybrid material functionalised with imidazolium cations displays a remarkable maximum surfactant adsorption of 1.5 mmol per gram of material at neutral pH.

      The influence of π-conjugation on the rates of long-range charge tunneling across rigid rod-like molecular bridges has been explored by a direct comparison of substituted and unsubstituted oligo-p-phenylene bridges.

    11. Redox-Active Complex Ligands

      On the Chemistry of the Strong Organic Electron-Donor 1,2,4,5-Tetrakis(tetramethylguanidino)benzene: Electron Transfer in Donor–Acceptor Couples and Binuclear Late Transition Metal Complexes (pages 3791–3800)

      Excellent electron-donor and redox-active complex ligand: 1,2,4,5-Tetrakis(tetramethylguanidino)benzene (ttmgb) is interesting for various applications. In this work we report on donor–acceptor salts and late-transition-metal complexes of ttmgb.

    12. Mn–Gd Complexes

      Structural and Magnetic Study of a Trinuclear MnII–GdIII–MnII Complex (pages 3801–3806)

      Jean-Pierre Costes, Javier Garcia-Tojal, Jean-Pierre Tuchagues and Laure Vendier

      Article first published online: 23 JUL 2009 | DOI: 10.1002/ejic.200900417

      Thumbnail image of graphical abstract

      A trinuclear MnII–GdIII–MnII complex, in which the gadolinium ion self-assembles with two Schiff base ligand MnII units, was characterized by structural determination. Only one ferromagnetic Mn–Gd interaction is active. This behaviour results from the presence of two very different double phenoxido Mn–Gd bridges. Oxidation of this complex does not yield the expected MnIII–GdIII–MnIII entity.

    13. Ruthenium–P,S-Donor Complexes

      The chemistry of phosphanyl–dioxolane and phosphanyl–dithiolane mixed P,S-donor ligands with the RuII precursors [RuCl2(PPh3)3] and [RuCl2(4-cymene)]2 is reported. Full characterisation of the resulting complexes by 1H, 13C and 31P NMR spectroscopy and X-ray crystallography is presented, and their activity as catalysts for hydrosilylation is examined.

      Thumbnail image of graphical abstract

      The new tetramethylplatinum(IV) complex [PtMe4(dppf)], in which the chelating dppf ligand is 1,1′-bis(diphenylphosphanyl)ferrocene, was treated with CF3COOH to give CH4, CH3–CH3, and the PtII complex [PtMe(OCOCF3)(dppf)].
