    1. Discrete Copper(I) Dimers

      Spectroscopic Evidence in Solid and Solution of a Discrete Copper(I) Tetrahedral Complex Dimer Supported by Supramolecular Interactions (pages 1579–1583)

      Danilo H. Jara, Luis Lemus, Liliana Farías, Eleonora Freire, Ricardo Baggio and Juan Guerrero

      Version of Record online: 1 MAR 2012 | DOI: 10.1002/ejic.201101356

      The self-association in a tetrahedral [Cu(N-{4-nitrophenyl}pyridine-2-yl-methanimine)(PPh3)Br] complex is reported. Experimental evidence for the dimerization in solution of this complex was obtained by NMR techniques. The dimer linked by noncovalent interactions has a close similarity to that in the crystalline packing. The thermodynamic parameters obtained by VT-1H NMR suggest that this process is enthalpy driven.

    2. Fluorescent Azobenzenes

      2,2′-Diborylazobenzenes with Double N–B Coordination: Control of Fluorescent Properties by Substituents and Redox Reactions (pages 1584–1587)

      A combined spectroscopic and theoretical method to study the binding mode of amino acids to a metal is discussed. Three compounds showing three metal sites: ferrous hexacoordinate, ferric pentacoordinate and ferrous pentacoordinate were studied. The work shows the subtle correlation between structure and the absorption edge features.

    2. Peroxomanganese(III) Complexes

      Steric and Electronic Influences on the Structures of Peroxomanganese(III) Complexes Supported by Tetradentate Ligands (pages 1598–1608)

      Robert A. Geiger, Gayan B. Wijeratne, Victor W. Day and Timothy A. Jackson

      Version of Record online: 15 FEB 2012 | DOI: 10.1002/ejic.201101391

      Thumbnail image of graphical abstract

      Peroxo-MnIII adducts are proposed as key intermediates in a variety of biologically and synthetically significant catalytic pathways. This work describes the synthesis and spectroscopic properties of a series of peroxo-MnIII complexes supported by a biologically relevant ligand system. Our results reveal that it is the steric properties of the supporting ligand affect the peroxo binding mode.

    3. Dual Luminescence

      Local Environments Around Eu3+ and Eu2+ Ions in Dual Light-Emitting BaSnO3:Eu Nanomaterials (pages 1609–1619)

      Dinesh Kanji Patel, Arijit Sengupta, Bathula Vishwanadh, Vasanthakumaran Sudarsan, Rajesh Kumar Vatsa, Ramakant Kadam and Shailendra Kumar Kulshreshtha

      Version of Record online: 10 FEB 2012 | DOI: 10.1002/ejic.201101240

      Thumbnail image of graphical abstract

      The incorporation of Eu3+ ions at Ba2+ sites in BaSnO3 generates cation vacancies in the lattice. The electrons present in some of the cation vacancies reduce Eu3+ to Eu2+ at the Ba2+ sites. Hence, at any instant, the BaSnO3 lattice will contain cation vacancies along with Eu3+ and Eu2+ ions occupying the Ba2+ sites, which leads to dual luminescence from the Eu ions.

    4. Guanidine-Functionalized Ligands

      Tuning the Properties of Redox-Active Guanidino-Functionalized Aromatic Ligands by Substitution: Experiment and Theory (pages 1620–1631)

      Eva-Maria Schnöckelborg, František Hartl, Thorsten Langer, Rainer Pöttgen and Robert Wolf

      Version of Record online: 17 FEB 2012 | DOI: 10.1002/ejic.201200001

      Thumbnail image of graphical abstract

      Naphthalene and anthracene bridges are present in the diiron sandwich compounds [Cp*Fe(μ-C10H8)FeCp*] (1) and [Cp*Fe(μ-C14H10)FeCp*] (2), which contain two formally 17e iron(I) centers that are strongly magnetically coupled. Cyclic voltammetry and UV/Vis spectroelectrochemistry show that neutral 1 and 2 can be reversibly oxidized to the monocations 1+ and 2+ as well as dications 12+ and 22+.

      Version of Record online: 21 FEB 2012 | DOI: 10.1002/ejic.201101295

      Thumbnail image of graphical abstract

      The one-pot solvothermal reactions of mixtures of zinc and copper salts and H2bdc and dabco linkers have led to the formation of novel mixed-metal [Zn1–xCux(bdc)(dabco)0.5] MOFs. The prepared materials are isostructural with the known layer-pillared monometallic [M(bdc)(dabco)0.5] (M = Zn or Cu) frameworks and exhibit permanent porosity.

    12. Functionalized Phosphido–Boranes

      Benzyl Ether-Substituted Phosphido–Borane Complexes of the Alkali Metals (pages 1696–1701)

      Keith Izod, James M. Watson, William Clegg and Ross W. Harrington

      Version of Record online: 21 FEB 2012 | DOI: 10.1002/ejic.201101367

      Thumbnail image of graphical abstract

      The synthesis of an ether-functionalized phosphane–borane and its lithium, sodium and potassium derivatives is reported. X-ray crystallography reveals that the binding mode of the phosphido–borane ligands is dependent on the nature of the metal center in each case.
