    1. Metalloid Clusters as Superatoms

      The Al50Cp*12 Cluster – A 138-Electron Closed Shell (L = 6) Superatom (pages 2649–2652)

      Peneé A. Clayborne, Olga Lopez-Acevedo, Robert L. Whetten, Henrik Grönbeck and Hannu Häkkinen

      Article first published online: 13 MAY 2011 | DOI: 10.1002/ejic.201100374

      Metal clusters stabilized by a surface ligand shell represent an interesting intermediate state of matter between molecular metal–ligand complexes and bulk metal. We show here that the known cluster Al50Cp*12 can be considered as an analogue to a giant atom (“superatom”) with 138 sp electrons organized in concentric angular momentum shells up to L = 6 symmetry.

    2. Antiferromagnetic Interactions

      Electrochemical and optical studies as well as multiphase transition behavior are reported for a series of new nickel bis(dithiolene) complexes. The effects of the nature and position of the functional groupsattached to the periphery of the complexes are investigated. X-ray diffraction measurements regarding the hexagonal columnar mesophase are reported.

    2. Electron and Spin Density Topology

      Electron and Spin Density Topology of the H-Cluster and Its Biomimetic Complexes (pages 2677–2690)

      Logan J. Giles, Alexios Grigoropoulos and Robert K. Szilagyi

      Article first published online: 13 MAY 2011 | DOI: 10.1002/ejic.201100318

      Thumbnail image of graphical abstract

      The electronic structures of the H-cluster and its biomimetic complexes were investigated by density functional theory calculations that use advanced electron and spin density analysis methods, such as Atoms-in-Molecule. We revealed a comprehensive picture of the complex network of intra- and intermolecular interactions that govern the electronic and magnetic properties of the H-cluster.

    3. Zinc Complexes

      New Binding Modes of 1-Acetyl- and 1-Benzoyl-5-hydroxypyrazolines – Synthesis and Characterization of O,O′-Pyrazoline- and N,O-Pyrazoline-Zinc Complexes (pages 2691–2697)

      Chika I. Someya, Shigeyoshi Inoue, Elisabeth Irran, Sebastian Krackl and Stephan Enthaler

      Article first published online: 4 MAY 2011 | DOI: 10.1002/ejic.201100248

      Thumbnail image of graphical abstract

      The versatility of 5-hydroxypyrazoline ligands has been demonstrated. Various zinc complexes have been synthesized and characterized resulting in new coordination modes of pyrazoline ligands depending on the reaction conditions; zinc dimers havebeen observed with a O,O′-coordination mode, whereas addition of tmeda to the reaction mixture led to the formation of a zinc-containing seven-membered ring system with an O,N-mode.

    4. UHV-STM on Ruthenium Complexes

      Metal Ion Coordinating Properties of the Highly Preorganized Tetradentate Ligand 1,10-Phenanthroline-2,9-dicarboxaldehyde-2,9-dioxime (pages 2706–02711)

      Lindsay L. Boone, Amy E. Mroz, Donald G. VanDerveer and Robert D. Hancock

      Article first published online: 6 MAY 2011 | DOI: 10.1002/ejic.201100090

      Thumbnail image of graphical abstract

      The structure of the PbII complex of PDOX (1,10-phenanthroline-2,9-dicarboxaldehyde-2,9-dioxime), a ligand that is preorganized for complexing large metal ions by formation of five-membered chelate rings, is reported. The large PbII ion is coordinated to both oxime nitrogen atoms, unlike PDOX complexes with small metal ions such as ZnII or CuII. Large metal ions stabilize their PDOX complexes more than their phen (1,10-phenanthroline) complexes.

    6. Metal-Organic Frameworks

      Solvothermal Synthesis and Structural Characterisation of Metal-Organic Frameworks with Paddle-Wheel Zinc Carboxylate Clusters and Mixed Ligands (pages 2712–2719)

      Article first published online: 12 MAY 2011 | DOI: 10.1002/ejic.201100227

      Thumbnail image of graphical abstract

      Five 3D interpenetrating metal-organic frameworks have been synthesized, and contain paddle-wheel zinc carboxylate clusters and mixed ligands, which can be regarded as nodes and linkers to generate a variety of topologies. The luminescence properties of the compounds have also been studied.

    7. Iron-Catalyzed Hydroxylation

      Substrate Hydroxylation by the Oxido–Iron Intermediate in Aromatic Amino Acid Hydroxylases: A DFT Mechanistic Study (pages 2720–2732)

      Elaine Olsson, Aurora Martinez, Knut Teigen and Vidar R. Jensen

      Article first published online: 2 MAY 2011 | DOI: 10.1002/ejic.201001218

      Thumbnail image of graphical abstract

      The mechanism of substrate hydroxylation by an FeIV=O intermediate in the aromatic amino acid hydroxylase (AAH) family of enzymes has been followed by DFT calculations. The mechanism begins with (Fe)O–C(substrate) bond formation, proceeds through an NIH shift and tautomerization to give the phenol product, and finally regenerates the catalyst by rebinding of ligating water molecules and dissociation of the oxidized cofactor.

    8. Thermoelectric Material

      Thermal Stability of High Performance Thermoelectric β-Zn4Sb3 in Argon (pages 2733–2737)

      Hao Yin, Birgitte L. Pedersen and Bo B. Iversen

      Article first published online: 10 MAY 2011 | DOI: 10.1002/ejic.201100130

      Thumbnail image of graphical abstract

      Multi-temperature synchrotron PXRD data were recorded to investigate the thermal stability of thermoelectric Zn4Sb3 heated in argon. About 95 wt.-% of original Zn4Sb3 is preserved after three heating cycles to 625 K for the sample heated in argon, while only ca. 40 wt.-% remains in the sample heated in air. Comparison of degradation behaviours for different samples suggests a two-process decomposition mechanism of Zn4Sb3.

    9. Enantioselective Catalysis

      Binuclear Pentalene Iron Carbonyl Complexes (pages 2746–2755)

      Huidong Li, Hao Feng, Weiguo Sun, Yaoming Xie, R. Bruce King and Henry F. Schaefer III

      Article first published online: 4 MAY 2011 | DOI: 10.1002/ejic.201100155

      Thumbnail image of graphical abstract

      The lowest energy C8H6Fe2(CO)6 structure is trans-(η55-C8H6)Fe2(CO)6 but a cis-(η51-C8H6)Fe2(CO)6 structure lies only ca. 3 kcal/mol above this global minimum. The experimentally known cis-(η55-C8H6)Fe2(CO)4(μ-CO) structure is found to be the lowest energy C8H6Fe2(CO)5 structure by more than 25 kcal/mol (BP86). Two triplet and two singlet cis-C8H6Fe2(CO)4 structures lie within 7 kcal/mol of each other (BP86) with the triplet structures having slightly lower energies.

    11. Oxidation Catalysis

      Guanidinium-Based Phosphotungstates and Ionic Liquids as Catalysts and Solvents for the Epoxidation of Olefins with Hydrogen Peroxide (pages 2756–2762)

      Loubna Gharnati, Olaf Walter, Ulrich Arnold and Manfred Döring

      Article first published online: 2 MAY 2011 | DOI: 10.1002/ejic.201100037

      Thumbnail image of graphical abstract

      Several guanidinium phosphotungstates and guanidinium-based ionic liquids have been synthesized and characterized. Their catalytic performance in epoxidation reactions with hydrogen peroxide was evaluated and compared to similar ammonium and imidazolium compounds. The reaction systems can be recycled and used in at least three consecutive reactions.

    12. Half-Sandwich Complexes

      Reactivity of a 16-Electron CpCo Half-Sandwich Complex Containing a Chelating 1,2-Dicarba-closo-dodecaborane-1,2-diselenolate Ligand towards FcC(O)C≡CH (pages 2763–2768)

      Hongde Ye, Wenjun Bai, Mingshi Xie, Yizhi Li and Hong Yan

      Article first published online: 17 MAY 2011 | DOI: 10.1002/ejic.201100159

      Thumbnail image of graphical abstract

      The reaction of the 16-electron half-sandwich complex CpCo(Se2C2B10H10) (1) with FcC(O)C≡CH leads to 4, which is able to further react with the alkyne in MeOH togenerate 5 containing a nido-C2B9 cluster. In the presence of silica, 4 can be converted to 6 with loss of the CpCo unit.

    13. Silicon-Containing Odorants

      Synthesis and Olfactory Characterization of Novel Silicon-Containing Acyclic Dienone Musk Odorants (pages 2769–2776)

      Marcel Geyer, Jennifer Bauer, Christian Burschka, Philip Kraft and Reinhold Tacke

      Article first published online: 4 MAY 2011 | DOI: 10.1002/ejic.201100161

      Thumbnail image of graphical abstract

      Compounds 1b1d [(di)sila analogues of the acyclic dienone musk odorant 1a] were synthesized and characterized for their olfactory properties. C/Si exchange had quite a dramatic effect on the musky-violet odor profile, and on the odor threshold. This indicates that the C-5 substituent is critical for a musky impression, whereas the substituent on C-6 has greater responsibility for floralcy.
