      The cover picture shows a representation of the HEWL–VIVO(pic)2 adduct (HEWL: hen egg white lysozyme). Our X-ray crystallography results show that the VIVO(pic)2 complex covalently binds to the COO– group of the side-chain Asp52 residue of HEWL. Although a relatively long VIV=O bond was obtained (ca. 1.82 Å), a combined approach using EPR and DFT techniques confirms that the carboxylate group of the Asp52 residue of HEWL binds to VIVO(pic)2 and, moreover, that the oxidation state of vanadium is VIV. We conclude that the long VIV=O bond obtained is the result of the exposure of the crystals to the very intense X-ray beam, which induces a progressive reduction of VIV to VIII and the concomitant bond elongation. These results may be important for the development of vanadium complexes as therapeutic agents, namely as oral insulin substitutes for the treatment of diabetes. We would like to thank Rui Pedro Bordalo for designing the cover picture. Details are discussed in the Short Communication by J. C. Pessoa, T. Santos-Silva et al. on p. 3293 ff.

      Vanadium complexes are recognized as insulin enhancers that can be transported by high-molecular-mass serum components. We report studies of the interaction of the antidiabetic vanadium(IV) picolinate complex with hen egg white lysozyme (HEWL). Soaked crystals diffracting up to a resolution of 1.28 Å show that VIV covalently binds to Asp52, two picolinate ions (pic), and an Ooxido atom.

      Transparent multifunctional phosphor films with multicolor tunability and superhydrophilic/antifogging properties have been fabricated by layer-by-layer assembly of RE-doped layered gadolinium hydroxide (LGdH:RE; RE = Eu and Tb) nanosheets and SiO2 nanoparticles on a quartz substrate.

    2. Luminescent Nanorods

      Hydrothermal Fabrication and Luminescence Properties of One-Dimensional TiO2:Eu3+ Spindlelike Nanorods (pages 3305–3311)

      A hydrothermal method is used to synthesize uniform TiO2:Eu3+ spindlelike nanorods for the first time. In the presence of citrate (Cit3–) ions and ethanediamine (en) molecules, the nanocrystals aggregate gradually through assembly and finally form well-defined TiO2:Eu3+ spindlelike nanorods.

    3. Environmental Chemistry

      Nuclear Magnetic Resonance Spectroscopy of Aqueous Plutonium(IV) Desferrioxamine B Complexes (pages 3312–3321)

      Mark A. Boggs, Harris Mason, Yuji Arai, Brian A. Powell, Annie B. Kersting and Mavrik Zavarin

      Article first published online: 16 JUN 2014 | DOI: 10.1002/ejic.201402105

      Thumbnail image of graphical abstract

      Two aqueous PuIV-desferrioxamine B (DFOB) complexes were characterized by 1D and 2D NMR techniques and a dimeric PuIVDFOB-di-μ-(O/OH)-PuIVDFOB complex was identified. Both “Curie” and “anti-Curie” behavior were observed for the dimeric species, yet the monomer only showed “anti-Curie”. Bond lengths and coordination numbers estimated from X-ray spectroscopic analysis support the proposed structures.

    4. Metal Oxides

      Aqueous Crystallization Strategy for Metastable h-MoO3 Crystals with Polyvinylpyrrolidone Induction (pages 3322–3329)

      Jingnan Guo, Yan Zhao, Jingzhe Zhao, Jiajing Wu, Yuehong Song, Yixin Tan, Fangping Wang, Xinli Hao, Yan Lu and Fengxia Bao

      Article first published online: 24 JUN 2014 | DOI: 10.1002/ejic.201402110

      Thumbnail image of graphical abstract

      Hexagonal MoO3 (h-MoO3) crystals are successfully prepared from (NH4)6Mo7O24·4H2O and HCl by a polyvinylpyrrolidone (PVP) induced aqueous route. The linear PVP molecules match the tunnel structure of metastable h-MoO3 crystals and enable crystallization in an aqueous solution at near-ambient temperatures. The photochromic properties of PVP-dependent samples of h-MoO3 crystals are studied.

    5. Solid-State NMR Spectroscopy

      Solid-State NMR Characterization of Paramagnetic Bis(L-valinato)copper(II) Stereoisomers – Effect of Conformational Disorder and Molecular Mobility on 13C and 2H Fast Magic-Angle Spinning Spectra (pages 3330–3340)

      Gábor Szalontai, Jasmina Sabolović, Marijana Marković and and Szabolcs Balogh

      Article first published online: 27 JUN 2014 | DOI: 10.1002/ejic.201402134

      The 13C and 2H fast magic-angle spinning (MAS) NMR spectra of paramagnetic bis(L-valinato)copper(II) complexes enable the distinction of trans and cis stereoisomers in the solid state. The study of deuterated bis(L-valinato)copper(II) complexes demonstrates the wealth of information available from the 2H MAS spectra of paramagnetic compounds, such as dynamic conformational changes inside the crystal lattice.

    6. Magnetic Properties

      The Impact of Anion-Modulated Structural Variations on the Magnetic Coupling in Trinuclear Heterometallic CuII–CoII Complexes Derived from a Salen-Type Schiff Base Ligand (pages 3341–3349)

      Soumavo Ghosh, Guillem Aromí, Patrick Gamez and Ashutosh Ghosh

      Article first published online: 16 JUN 2014 | DOI: 10.1002/ejic.201402151

      Thumbnail image of graphical abstract

      Anion-mediated geometrical variations generate three heterometallic complexes with distinct trinuclear Cu2Co cores as a result of different diphenoxido bridging angles between the CuII and CoII ions. Magnetic studies reveal decreased antiferromagnetic exchange interactions associated with a decrease of this bridging angle.

      The reaction of 6-formyl-2-(hydroxymethyl)-4-methylphenol with appropriate lanthanide salts followed by reaction with Ni(OAc)2·4H2O affords pentanuclear heterobimetallic compounds containing a [Ni4Ln] core. These complexes have a distorted tetragonal core structure in which the M–O–M′ (M′ = NiII/LnIII) angles are around 90°.

    12. Self-Organization

      Chang-Gen Lin, Wei Chen and Yu-Fei Song

      Article first published online: 17 JUN 2014 | DOI: 10.1002/ejic.201402239

      Thumbnail image of graphical abstract

      New polyoxometalate-based amphiphiles with Anderson cluster head groups are synthesized by covalently tethering alkyl chains onto the Anderson cluster. In CH3CN/H2O mixtures, these amphiphiles show intriguing morphologies that can be finely tuned. The structural conformation, hydrophobic–hydrophobic interactions, and solvent polarity profoundly influence the self-organization of these amphiphiles.

      The C3v B3O3X3V, D3d [B3O3X3]2V, and [B3O3X3]3V2 (X = H, BO) are favored in energy and could be targeted in future experiments. The sandwich structural pattern developed in this work expands the structural domain of transition-metal complexes by introducing inorganic B3O3H3 and B3O3(BO)3 into traditional sandwich-type structures and may be extended to [B3O3X3]nVn–1 (n ≥ 4), which could act as linear magnetic wires.

The spirosilanes are used for successful protodeborylation reaction. The characteristic NMR spectroscopic data for all compounds are collected, and the X-ray structures of some examples are determined.

      Junhui Liu, Qidong Zhang, Peng Li, Zhan Qu, Shihao Sun, Yuping Ma, Dongying Su, Yongli Zong and Jianxun Zhang

      Article first published online: 17 JUN 2014 | DOI: 10.1002/ejic.201402093

      Thumbnail image of graphical abstract

      The combination of the sila-substitution concept with the insertion reactions of terminal alkynes into silacyclobutane efficiently led to the sila-odorants Si-Artemone, Si-β-Dynascone, and Si-Herbac. Si-Artemone and Si-Herbac have sensory characters similar to those of their unsubstituted analogues, whereas Si-β-Dynascone has an odor quite different to that of its unsubstituted analogue.
