      The cover picture shows the unit cell of a layered dysprosium hydroxide material, Dy8(OH)20Cl4·6H8O, viewed along the b axis (left) and the c axis (right). The SEM image indicates the high crystallinity of the particles. The temperature dependence of the imaginary component of the AC susceptibility (χ) under zero DC field and the magnetic field dependence of the magnetization (M) are just two indicators that this is the first example of a layered lanthanide compound showing single-molecule-magnet (SMM) behavior. This feature adds new potential applications to these materials in molecular spintronics and quantum computing. Details are discussed in the Short Communication by M. Almeida et al. on p. 5059 ff.

      Dy8(OH)20Cl4·6H2O, a layered lanthanide hydroxide, shows slow magnetic relaxation at low temperatures with a blocking temperature of 3 K and an energy barrier of 36.1 K, a behavior characteristic of single-molecule magnets. This is the first example of a layered rare earth compound with such behavior.

      Moema B. S. Botelho, Maria D. Gálvez-López, Luisa De Cola, Rodrigo Q. Albuquerque and Andrea S. S. de Camargo

      Article first published online: 2 SEP 2013 | DOI: 10.1002/ejic.201300681

      Thumbnail image of graphical abstract

      The synthesis of a tridentate ligand exhibiting appropriate spectral properties has led to the formation of a neutral, nine-coordinate Eu3+ complex that exhibits one of the largest emission quantum yields ever reported in solution, Φ = 85 %. Photophysical measurements and ligand field calculations were also made to characterize this highly luminescent complex.

    3. Main Group Chemistry

      Article first published online: 6 SEP 2013 | DOI: 10.1002/ejic.201300841

      Thumbnail image of graphical abstract

      A simple condensation reaction between ethyl phosphate and arylboronic acids is used to synthesize molecular borophosphates of the formula [(EtPO3BAr)6]. The compounds display a cage structure, which is stabilized by the alkyl and aryl groups on the cage surface.

    4. Pincer Complexes

      Structures and Dynamics of the Mixed Dihydrogen/Hydride Complexes [Ru(PCP)(H)(H2)n] (n = 1, 2) and [Ru(PNP)(H)2(H2)] (pages 5075–5080)

      Thumbnail image of graphical abstract

      “Watching” hydrides and hydrogen molecules in the vicinity of a transition metal as in 1 and 2 is fascinating to chemists, as in many cases only demanding diffraction techniques such as neutron diffraction give a satisfying answer. DFT calculations can help to understand significantly the structures and dynamics of such seemingly simple complexes and nicely support and confirm solid-state analytics.

    5. Metal–Organic Frameworks

      Infinite Metal–Carboxylate Nanotube Constructed Metal–Organic Frameworks and Gas Sorption Properties (pages 5081–5085)

      Xiaoxia Lv, Sifu Tang, Liangjun Li, Jinjun Cai, Chao Wang, Xianrui Xu and Xuebo Zhao

      Article first published online: 30 AUG 2013 | DOI: 10.1002/ejic.201300714

      Thumbnail image of graphical abstract

      Two isomorphic microporous metal–organic frameworks based on a metal–carboxylate nanotube were synthesized by the reaction of an aminopolycarboxylate ligand with Co and Ni hydroxides under hydrothermal conditions. The two isostructural frameworks exhibit stability up to 350 °C, and sorption studies for N2, H2, CO2, and CH4 confirmed their permanent porosity.

      Mariana Derzsi, Andreas Hermann, Roald Hoffmann and Wojciech Grochala

      Article first published online: 21 AUG 2013 | DOI: 10.1002/ejic.201300769

      Thumbnail image of graphical abstract

      The structural relations of (and between) late transition metal monoxides, MO, and monosulfates, MSO4, are analyzed. We show that all of these late transition metal oxides, as well as 4d and 5d metal sulfates, crystallize in distorted rock salt lattices and argue that the distortions are driven by collective first- and/or second order Jahn–Teller effects, as quantified by the c′/a′ ratio.

    3. Metal–Organic Frameworks

      Two cobalt-based metal–organic frameworks were synthesized and characterized by single-crystal X-ray diffraction analysis. Both compounds show an interesting 7-c net structure and are catalytically active towards epoxidation reactions, and they can be recycled up to five times without loss of activity.

      Thumbnail image of graphical abstract

      The characteristics of complexes formed by 3-(4-X-phenyl)-2-sulfanylpropenoic acids with lead(II) cations have been explored both in the solid state and in solution. The importance of the stereochemically active lone electron pair of the PbII ion in the supramolecular arrangement of [HQ]2[Pb(X-pspa)2] (X = Cl, Br; Q = diisopropylamine) is discussed.

      Thumbnail image of graphical abstract

      A bis(bidentate) tetraphosphane produces heterodi- or heterotrinuclear species in one step depending on its oxidation state. These supramolecular arrays consist of chromophores and reactive metal centres. To understand the versatility of the tetraphosphane, a further partly oxidized derivative of it is also investigated.

      Thumbnail image of graphical abstract

      Decomposition of zinc hydroxide acetate dihydrate in ethanol can be exploited to generate ZnO nanoparticles at room temperature. The mechanism involves the removal of waters of hydration and the formation of Zn5(OH)8(CH3CO2)2 followed by the generation of Zn(CH3CO)2 and ZnO.

      Reactions of copper(I) halides (Cl, Br), [CuI(NCCH3)4](BF4), and copper(II) nitrate with thiazolidine-2-thione, 1-methylimidazoline-2-thione, and imidazolidine-2-thione in different solvents result in C–S bond cleavage and the in situ production of sulfate. For example, thiazolidine-2-thione is transformed into a new thio ligand, 3-(2-thiazolin-2-yl)thiazolidine-2-thione, which forms compounds 1 and 2 depending on the anion.
