      The cover picture shows the deposition of palladium nanoparticles (Pd NPs) on the surface of carbon nanotubes (CNTs) by a simple strategy employing ethanol as the solvent/reducing agent, potassium tetrachloropalladate(II) (K2PdCl4) as the Pd precursor, and polyvinylpyrrolidone (PVP) as the surface modifier. More specifically, the approach is based on the nonbonding interaction between PVP and the CNTs and does not require any additional functionalization steps, reducing agents, or stabilizers to uniformly distribute Pd NPs on the CNTs. Details are discussed in the article by S. J. Haigh, P. H. C. Camargo et al. on p. 1439 ff. For more on the story behind the cover research, see the Cover Profile.

      Thumbnail image of graphical abstract

      The nonbonding interaction between polyvinylpyrrolidone (PVP) and multiwalled carbon nanotubes (MWCNTs) was employed to achieve deposition of palladium nanoparticles less than 5 nm in size over the surface of the MWCNTs; with ethanol as the solvent/reducing agent, potassium tetrachloropalladate(II) as the precursor, and PVP as the surface modifier.

    2. Polymerisation Catalysis

      Efficient Synthesis of Aluminium-Terminated Polyethylene by Means of Irreversible Coordinative Chain-Transfer Polymerisation Using a Guanidinatotitanium Catalyst (pages 1446–1453)

      Version of Record online: 11 FEB 2014 | DOI: 10.1002/ejic.201301610

      Thumbnail image of graphical abstract

      A series of novel mono(guanidinato)titanium(IV) complexes has been synthesised and characterised. Single-crystal analyses were performed for all complexes. Compound 4a showed very high activities in the polymerisation of ethylene in the presence of very high amounts of aluminium after activation with fluorinated borates. Irreversible coordinative chain transfer to aluminium was observed.

    3. Ruthenium Complexes

      Ruthenium–Nitrosyl Complexes Derived from Ligands Containing Two Carboxylate Functional Groups and Studies on the Photolability of Coordinated NO (pages 1454–1461)

      Ru–nitrosyl complexes [Ru(L1)(PPh3)2(NO)](ClO4) (1a) and [Ru(L2)(PPh3)2(NO)](ClO4) (2a) with a {RuNO}6 moiety were synthesized, and the crystal structure of 2a was determined. Photoreleased nitric oxide was quantified by Griess reaction; the amount of generated reactive N and/or O species was estimated by 2,2-diphenyl-1-picrylhydrazine (DPPH) radical quenching assay during photodissociation of NO.

    4. Benzopyrene–Chromium Complexes

      Chromium Complexes Containing Polycyclic Condensed Aromatic Ligands: Mono- and Bidirectional Synthesis from Chromium–Carbenes, Molecular Structures, and Rearrangement Reactions (pages 1462–1469)

      Peter Hegele, Gregor Schnakenburg, Jörg Daniels and Karl Heinz Dötz

      Version of Record online: 11 FEB 2014 | DOI: 10.1002/ejic.201301409

      Thumbnail image of graphical abstract

      A benzannulation/metal migration sequence allows the thermocontrolled regioselective transformation of pyrenylcarbene–chromium into hydroquinoid benzopyrene–chromium complexes. Bidirectional extension of the protocol to a 1,8-pyrenediylbis(carbene) complex affords syn- and anti-dinuclear dibenzopyrene–Cr(CO)3 complexes. TBDMS = tert-butyldimethylsilyl, Tf = trifluoromethylsulfonyl.

    5. Electron Transfer

      Electron Transfer from Excited [Ir(2-phenylpyridyl)3] through a Coexisting Electron Relay in Zeolite (pages 1470–1476)

      Chen Xu, Dai Mochizuki, Masato M. Maitani and Yuji Wada

      Version of Record online: 24 FEB 2014 | DOI: 10.1002/ejic.201301431

      Photoinduced electron transfer was investigated between an ortho-metalated IrIII complex encapsulated in the supercage of faujasite zeolite dispersed in solution and viologen derivatives dissolved in the solution.

    6. Macrocycle Sensors

      Boron Macrocycles Based on Multicomponent Assemblies using (3-Aminophenyl)boronic Acid and Pentaerythritol as Common Reagents; Molecular Receptors toward Lewis Bases (pages 1477–1484)

      Norma A. Celis, Carolina Godoy-Alcántar, Jorge Guerrero-Álvarez and Victor Barba

      Version of Record online: 12 FEB 2014 | DOI: 10.1002/ejic.201301450

      Thumbnail image of graphical abstract

      Multicomponent reactions using arylboronic acids, pentaerythritol, and aromatic aldehyde derivatives form well-defined macrocyclic structures. The molecules allow encapsulation of neutral species within their cavity through noncovalent interactions, however, the presence of acid and base Lewis centers within the structures enable their use as ditopic molecular receptors.

    7. Chiral Metallodrugs

      Cytotoxic Titanium(IV) Complexes of Chiral Diaminobis(phenolato) Ligands: Better Combination of Activity and Stability by the Bipyrrolidine Moiety (pages 1485–1491)

      Thumbnail image of graphical abstract

      Racemic and optically pure phenolato titanium(IV) complexes were prepared with NH, NMe, and bipyrrolidine-based diamino bridges. The optically pure bipyrrolidine complexes provide the best combination of hydrolytic stability and biological activity, presumably by maintaining small enough steric bulk to enable biological accessibility.

    8. Coordination Chemistry

      Version of Record online: 24 FEB 2014 | DOI: 10.1002/ejic.201301549

      Thumbnail image of graphical abstract

      peri-Substituted acenaphthylenes [Acenapyl(X)(EPh)] and [Acenapyl(EPh)(E′Ph)] have been prepared and molecular structures determined where possible. Comparison with analogous naphthalene and acenaphthene compounds reveals similar trends. Under appropriate geometric conditions, quasilinear CPh–E···Z (E = Te, Se, S; Z = Br/E) fragments exist to promote attractive 3c–4e interactions.

    11. Ruthenium–NHC Complexes

      Synthesis and Reactivity of Cationic Bis(N-Heterocyclic Dicarbene) Ruthenium(II) Complexes (pages 1524–1532)

      Cristina Tubaro, Davide Bertinazzo, Marco Monticelli, Omar Saoncella, Andrea Volpe, Marino Basato, Denis Badocco, Paolo Pastore, Claudia Graiff and Alfonso Venzo

      Version of Record online: 19 FEB 2014 | DOI: 10.1002/ejic.201301583

      The transfer of a di-N-Heterocyclic carbene (diNHC) ligand from silver complexes to ruthenium(II) derivatives {[RuCl2(COD)]x or [RuCl2(p-cymene)]2 (COD = 1,5-cyclooctadiene)} affords cationic cis- or trans-bis(diNHC)ruthenium(II) complexes, depending on the nature of the linker between the two imidazol-2-ylidene rings.

    12. Separation

      Thermodynamical Criteria of the Higher Selectivity of Zirconium Oxycations over Hafnium Oxycations towards Organophosphorus Ligands: Density Functional Theoretical Investigation (pages 1533–1545)

      Sk. Musharaf Ali

      Version of Record online: 19 FEB 2014 | DOI: 10.1002/ejic.201301630

      Thumbnail image of graphical abstract

      Free energy analysis of a thermodynamical cycle and DFT calculations with the conductor-like screening model (COSMO) capture the experimental selectivity of ZrO2+ ions over HfO2+ ions towards tributyl phosphate (TBP) and Cyanex925 ligands. The selectivity between the two ligands for a particular metal oxycation is independent of the solvation pattern of the oxycation.

    13. Phthalocyanine

      Planar Binuclear Phthalocyanine-Containing Sandwich-Type Rare-Earth Complexes: Synthesis, Spectroscopy, Electrochemistry, and NLO Properties (pages 1546–1551)

      Version of Record online: 24 FEB 2014 | DOI: 10.1002/ejic.201301485

      Thumbnail image of graphical abstract

      Three new binuclear phthalocyanine-containing sandwich-type rare-earth complexes have been synthesized and spectroscopically and electrochemically characterized. The good third-order nonlinear optical property revealed for the praseodymium species suggests it has potential applications in the optical-limiting field.

    14. Schiff Base Complexes

      Two Tetranuclear Copper(II) Complexes with Open Cubane-Like Cu4O4 Core Framework and Ferromagnetic Exchange Interactions between Copper(II) Ions: Structure, Magnetic Properties, and Density Functional Study (pages 1552–1560)

      Version of Record online: 24 FEB 2014 | DOI: 10.1002/ejic.201301515

      Thumbnail image of graphical abstract

      Two alkoxo-bridged copper(II) tridentate Schiff base complexes were synthesized and structurally and magnetically characterized. Magnetic susceptibility measurements on the tetranuclear complexes indicate ferromagnetic exchange coupling between copper(II) centers. The sign and magnitude of the exchange coupling constants were justified on the basis of several factors including DFT calculations.
