    1. Magnetic Anisotropy

      Metallocenium Salts of Nickel Bis(α-thiophenedithiolate) [M(Cp*)2][Ni(α-tpdt)2] (M = Fe, Mn, Cr) – Metamagnetism and Magnetic Frustration (pages 5327–5337)

      Dulce Belo, Joana Mendonça, Isabel C. Santos, Laura Cristina Jesus Pereira, Manuel Almeida, Juan J. Novoa, Concepció Rovira, Jaume Veciana and Vasco Gama

      Article first published online: 10 SEP 2008 | DOI: 10.1002/ejic.200800621

      [M(Cp*)2][Ni(α-tpdt)2] [M = Fe (1), Mn (2), Cr (3)] show similar multilayer structural arrangements, but at low temperatures, 1 is a metamagnet, 2 is a frustrated magnet, and 3 is a paramagnet. The unusual behavior of 2 is due to a degenerate ground state resulting from interlayer chain arrangements and magnetic anisotropy.

    2. Mechanism of Nitrate Reduction

      The Role of Axial Ligation in Nitrate Reductase: A Model Study by DFT Calculations on the Mechanism of Nitrate Reduction (pages 5338–5349)

      Kuntal Pal and Sabyasachi Sarkar

      Article first published online: 27 OCT 2008 | DOI: 10.1002/ejic.200800514

      Thumbnail image of graphical abstract

      Computational studies on the binding of substrates to some functional models of nitrate reductase support the experimental findings concerning the formation of aMichaelis-type complex. The calculated energy profile of this type of reaction shows the necessity of axial thiolate coordination in contrast to halide coordination.

    3. Explosives

      1,2,4-Triazolium and Tetrazolium Picrate Salts: “On the Way” from Nitroaromatic to Azole-Based Energetic Materials (pages 5350–5366)

      Thomas M. Klapötke and Carles Miró Sabaté

      Article first published online: 27 OCT 2008 | DOI: 10.1002/ejic.200800771

      Thumbnail image of graphical abstract

      The energetic properties of picrate salts with azolium cations were studied. The compounds combine the high thermal stabilities of classical nitroaromatic energetic materials with relatively high performances. All compounds also proved to be insensitive and higher performing than TNT or picric acid and were predicted to yield less decomposition residue, with potential for energetic applications.

    4. Spirosilane Derivatives

      Combination of 1,2-Hydroboration and 1,1-Organoboration: A Convenient Route to 5-Silaspiro[4,4]nona-1,6-diene Derivatives (pages 5367–5372)

      Ezzat Khan, Bernd Wrackmeyer and Rhett Kempe

      Article first published online: 29 OCT 2008 | DOI: 10.1002/ejic.200800790

      Thumbnail image of graphical abstract

      Dialkyn-1-yl(divinyl)silanes react with 9-borabicyclo[3.3.1]nonane (9-BBN) by 1,2-hydroboration followed by intramolecular 1,1-organoboration to give 5-silaspiro[4.4]nona-1,6-diene derivatives. Protodeborylation with excess acetic acid affords the respective spirosilanes bearing substituents only in 1,6-positions. Multinuclear NMR spectroscopy (1H, 11B, 13C, 29Si NMR) and X-ray structural analysis served for the characterization of the new spirosilanes.

    5. Vanadates in ILs

      On the Nature of VV Species in Hydrophilic Ionic Liquids: A Spectroscopic Approach (pages 5373–5381)

      István Bányai, Valeria Conte, Lage Pettersson and Adriano Silvagni

      Article first published online: 27 OCT 2008 | DOI: 10.1002/ejic.200800673

      Thumbnail image of graphical abstract

      Heteronuclear NMR experiments, in particular 51V, were performed with the aim to elucidate the nature of vanadates and peroxovanadates in hydrophilic ionic liquids, that is, [bmim][BF4], [bmim][TfO] and [bdmim][BF4].

    6. LIESST Studies

      Influence of Metal Dilution on the Light-Induced Spin Transition in Two 1D Chain Compounds: [FexZn1–x(btzp)3](BF4)2 and [FexZn1–x(endi)3](BF4)2 {btzp = 1,2-Bis(tetrazol-1-yl)propane and endi = 1,2-Bis(tetrazol-1-yl)ethane} (pages 5382–5389)

      Chérif Baldé, Cédric Desplanches, Matthias Grunert, Yongli Wei, Philipp Gütlich and Jean-François Létard

      Article first published online: 22 OCT 2008 | DOI: 10.1002/ejic.200800570

      Thumbnail image of graphical abstract

      Thermal spin transition and Light-Induced Excited Spin State Trapping (LIESST) studies have been undertaken on a series of zinc-diluted polymeric chain iron(II)complexes. The relationship between T(LIESST) and dilution by zinc(II) on these systems is discussed.

    7. Compartmental Ligand Scaffolds

      Bulky Pyrazolate-Based Compartmental Ligand Scaffolds: Encapsulation of an Edge-Sharing Cu6O2 Bitetrahedral Core (pages 5390–5396)

      Anna Sachse, Gilles Noël, Sebastian Dechert, Serhiy Demeshko, Andreas Honecker, Alexei Alfonsov, Vladislav Kataev and Franc Meyer

      Article first published online: 23 OCT 2008 | DOI: 10.1002/ejic.200800655

      Thumbnail image of graphical abstract

      Using pyrazolate ligands with appended bulky imine donor side arms, novel hexanuclear CuII complexes with an unusual {Cu64-O)2}-bitetrahedral core were obtained, and their structures determined by X-ray crystallography. Magnetic and high-field EPR data reveal an overall S = 0 ground state with the first excited triplet at ΔE ≈ 95 cm–1.

    8. Divalent Group 14 Species

      Germylenes and Stannylenes with Chelating Anilido–Imine Ligands: Syntheses, Structures and Reactivity (pages 5397–5403)

      Ali Mcheik, Nadia Katir, Annie Castel, Heinz Gornitzka, Stéphane Massou, Pierre Rivière and Tayssir Hamieh

      Article first published online: 22 OCT 2008 | DOI: 10.1002/ejic.200800723

      Thumbnail image of graphical abstract

      The anilido–imine ligand has proved to be particularly effective in the stabilization of divalent group 14 compounds into their monomeric form. NMR spectroscopy and X-ray analysis highlight the perfect chelation of the ligands and the formation of a three-coordinate metal. These complexes preserve their specific reactivity of low-coordinate group 14 species.

    9. Heme Peroxidases

      Halide Activation by Heme Peroxidases: Theoretical Predictions on Putative Adducts of Halides with Compound I (pages 5404–5407)

      Radu Silaghi-Dumitrescu

      Article first published online: 23 OCT 2008 | DOI: 10.1002/ejic.200800732

      Thumbnail image of graphical abstract

      DFT results on models of the FeIII–OX and FeIII–HOX (X = halogen) adducts of chloroperoxidase and myeloperoxidase are reported. The O–X bonds are very weak, and a ‘caged' adduct, with a FeIII speciesclose to the oxidized halide, is a likely alternative for the intermediate in CPO and MPO. The presence of a trans axial thiolate or imidazole ligand appears to have an effect on halide activation.

    10. Pyrazolate Gold Complexes

      Coordination Behaviour of Gold and Silver Towards Pyrazole Ligands (pages 5408–5417)

      Olga Crespo, M. Concepción Gimeno, Peter G. Jones, Antonio Laguna, Mar Naranjo and M. Dolores Villacampa

      Article first published online: 22 OCT 2008 | DOI: 10.1002/ejic.200800578

      Several gold(I), gold(III) and silver(I) complexes with pyrazole or pyrazolate ligands have been synthesized and structurally characterized.

    11. Carbene Complexes

      Efficient Transfer Hydrogenation Using Iridium and Rhodium Complexes of Benzannulated N-Heterocyclic Carbenes (pages 5418–5423)

      Hayati Türkmen, Tania Pape, F. Ekkehardt Hahn and Bekir Çetinkaya

      Article first published online: 29 OCT 2008 | DOI: 10.1002/ejic.200800715

      Thumbnail image of graphical abstract

      Iridium and rhodium complexes with symmetrically and unsymmetrically substituted benzimidazolin-2-ylidene ligands like 3a were prepared and studied in the catalytic transfer hydrogenation of acetophenone and cyclohexanone by using isopropyl alcohol as the hydrogen source.
