      The cover picture shows two dissymmetric bis(3-pyridyl) ligands based on a planar chiral pseudo-ortho-disubstituted [2.2]paracyclophane scaffold. Upon coordination to metal centers like palladium(II) ions that prefer a square-planar coordination, these ligands act as trans-chelating ligands as proven by the formation of mononuclear [ML2] complexes. Interestingly, this process occurs with complete chiral self-sorting in a narcissistic self-recognition manner. The background shows a statue of August Kekulé in front of the historical building of the chemical institute in Bonn. Details are discussed in the article by A. Lützen et al. on p. 2495 ff. For more on the story behind the cover research, see the Cover Profile.

      Xiang-Guang Guo, Wen-Bin Yang, Xiao-Yuan Wu, Lang Lin and Can-Zhong Lu

      Version of Record online: 24 APR 2014 | DOI: 10.1002/ejic.201402128

      Two new compounds, one with a 3D/3D hetero-interpenetrating diamondoid framework and the other with a homo-interpenetrating pcu network, are synthesized through a one-pot reaction. Their pure phases are obtained by adjusting the metal/ligands ratio. The magnetic properties of the homo-interpenetrating network are investigated.

      Unsymmetrical diboranes(4) of the type {pinB–B[(NR)2C6H4]} are used as precursors for the selective synthesis of unprecedented unsymmetrical PtII diboryl and diaminoboryl CuI complexes by oxidative addition and σ-bond metathesis reactions, respectively. A versatile and modular route to the unsymmetrical diborane(4) compounds used is described; pin = pinacolato, Dipp = 2,6-diisopropylphenyl, IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene.

      Chiral Self-Sorting of trans-Chelating Chiral Ligands upon Formation of PdII Complexes (pages 2495–2501)

      Georg Meyer-Eppler, Filip Topić, Gregor Schnakenburg, Kari Rissanen and Arne Lützen

      Version of Record online: 9 APR 2014 | DOI: 10.1002/ejic.201402057

      Thumbnail image of graphical abstract

      Two bis(3-pyridyl) ligands based on a planar chiral [2.2]paracyclophane scaffold act as trans-chelating ligands for square-planar-coordinated metal centres such as palladium(II) ions. (Pseudo)racemic ligands undergo complete chiral self-sorting in a narcissistic self-recognition manner upon forming mononuclear homochiral [PdL2] complexes.

    2. Metathesis Reactions

      Theoretical Investigation of the Controlled Metathesis Reactions of Methylruthenium(II) Complexes with Terminal Acetylenes (pages 2502–2511)

      Yuxia Liu, Guang Chen, Hongliang Wang, Siwei Bi and Dongju Zhang

      Version of Record online: 22 APR 2014 | DOI: 10.1002/ejic.201400123

      Thumbnail image of graphical abstract

      DFT calculations have been performed to study the controlled metathesis mechanisms of trans-[Ru(CH3)2(dmpe)2] [dmpe = 1,2-bis(dimethylphosphanyl)ethane] with terminal acetylenes. Two important issues have been addressed, one of which is the role methanol plays in promoting the ligand metathesis between the methyl group and one alkynyl moiety.

    3. Gold Antitumor Agents

      Synthesis, Characterization, and Cytotoxic Activity of AuI N,S-Heterocyclic Carbenes Derived from Peptides Containing L-Thiazolylalanine (pages 2512–2519)

      Alejandro Gutiérrez, M. Concepción Gimeno, Isabel Marzo and Nils Metzler-Nolte

      Version of Record online: 22 APR 2014 | DOI: 10.1002/ejic.201402103

      Thumbnail image of graphical abstract

      The first organometallic gold(I) bioconjugates of a thiazole-based peptide are reported. The N,S-heterocyclic carbene gold(I) derivatives were prepared from the corresponding thiazolium peptide salts either by following the Ag2O route or by reaction with a strong base. The new compounds display excellent in vitro cytotoxicity with IC50 values as low as 0.4 μM.

      Version of Record online: 11 APR 2014 | DOI: 10.1002/ejic.201402169

      The forces that control the self-assembly between dicarboxylate guests and dinuclear lanthanide complexes are explored and are more complicated than anticipated.

    5. Ru(II) Complex Formation

      Kinetics and Mechanism of the Reduction of mer-Tris-picolinatoruthenium(III) by L-Ascorbic Acid (pages 2529–2535)

      Anna Katafias, Olga Impert, Przemysław Kita, Joanna Fenska, Stanisław Koter, Anna Kaczmarek-Kędziera, Henryk Różycki, Anna Bajek, Małgorzata Uzarska and Rudi van Eldik

      Version of Record online: 17 APR 2014 | DOI: 10.1002/ejic.201301556

      Thumbnail image of graphical abstract

      The reduction of mer-tris-picolinatoruthenium(III) by L-ascorbic acid as a function of pH can only be studied under well-selected reaction conditions to prevent the back-oxidation of tris-picolinatoruthenium(II) caused by traces of dioxygen. Under such conditions, the redox activity of L-ascorbic acid (AscH2) follows the sequence AscH2 << AscH << Asc2–.

      Version of Record online: 28 APR 2014 | DOI: 10.1002/ejic.201400014

      Thumbnail image of graphical abstract

      The binary metal cyanurate Ba3(O3C3N3)2 was synthesized by a solid-state metathesis reaction, and the nature of the cyanurate ion was examined by density functional methods.

    7. Multibranched Structures

      Nonlinear Optical Properties of Conjugated Platinum(II) Acetylides with Multibranched Donor–Acceptor Structures (pages 2544–2551)

      Puhui Xie, Lingyu Wang, Zhaohui Huang, Fengqi Guo and Qiu Jin

      Version of Record online: 28 APR 2014 | DOI: 10.1002/ejic.201402043

      Thumbnail image of graphical abstract

      Six conjugated platinum(II) acetylides with multibranched donor-acceptor structures were synthesized. Their geometries were optimized and the HOMO and LUMO were calculated using the DFT method. The photophysical properties, time resolved transient absorption properties and the nonlinear optical properties were studied systematically.

    8. Magnetic Properties

      Probing the Influence of the Ligands on the Magnetism of Dinuclear Manganese, Iron, and Chromium Complexes Supported by Aroylhydrazone (pages 2552–2560)

      Alex Domingo, David Specklin, Vitor Rosa, Samir Mameri, Vincent Robert and Richard Welter

      Version of Record online: 23 APR 2014 | DOI: 10.1002/ejic.201402084

      Thumbnail image of graphical abstract

      The influence of the different molecular regions of five dinuclear complexes constructed with aroylhydrazone ligands is explored through ab initio wave function calculations with localized orbitals. The role of the ligands is key to control the structure of the dimetallic core and, thus, determines the overall magnetism.

    9. Co Cluster Compounds

      Magnetic Study of a Pentanuclear {Co2IIICo3II} Cluster with a Bent {CoII3} Motif (pages 2561–2568)

      Irene C. Lazzarini, Alejandro V. Funes, Luca Carrella, Lorenzo Sorace, Eva Rentschler and Pablo Alborés

      Version of Record online: 11 APR 2014 | DOI: 10.1002/ejic.201402089

      Thumbnail image of graphical abstract

      We report a new pentanuclear mixed-valent cobalt cluster exhibiting a {CoII3CoII2} core that can be conveniently described as two fused Co3–μ3–OH triangles with a strict unique sharing vertex point. We have analysed its magnetic behaviour by combining susceptibility, magnetisation and EPR data as well as broken-symmetry DFT calculations.

    10. Ge(IV) Complex Degradation

      The Thermal Stability of Tris(methimazolyl)borates and Their Germanium Complexes (pages 2569–2575)

      Dawn Wallace, Kirsten Chalmers, Christopher A. Dodds, Iain A. Stepek, David R. Armstrong, Leonard E. A. Berlouis, John Reglinski and Mark D. Spicer

      Version of Record online: 8 APR 2014 | DOI: 10.1002/ejic.201301588

      Thumbnail image of graphical abstract

      A series of at-boron substituted soft scorpionate ligands ([RTmMe]) and their germanium(IV) complexes are reported and their thermal degradation explored. Two degradation pathways are observed; it is proposed that one involves alkyl migration (R = Me, nBu) whereas the other pathway proceeds by heterocycle formation (R = H, Ph).

      Subodh Ganesanpotti, Cédric Tassel, Naoaki Hayashi, Yoshihiro Goto, Guillaume Bouilly, Takeshi Yajima, Yoji Kobayashi and Hiroshi Kageyama

      Version of Record online: 10 APR 2014 | DOI: 10.1002/ejic.201402009

      Thumbnail image of graphical abstract

      High-pressure oxygen intercalation of a brownmillerite phase Ca2Fe1.1Mn0.9O5 provides a fully oxidized layered double perovskite Ca2Fe1.1Mn0.9O6 with alternate Fe4+(d4) and Mn4+(d3) layers. Ca2Fe1.1Mn0.9O6 exhibits charge disproportionation and magneto-resistivity. Electron hopping through double-exchange ferromagnetic interactions between Fe4+ and Mn4+ is proposed.
