      The cover picture shows the adsorption-based separation of ethylene from ethane by [Cu2(2,3-pyrazinedicarboxylate)2(pyrazine)]n (CPL-1), which was investigated with both single and binary gas systems. The separation originates from the difference in the hydrogen bonding between CPL-1 and C2 hydrocarbons, which were confirmed by spectroscopic and computational methods. The background is a view of the Oita chemical complex where cryogenic distillation of ethylene is conducted every day. The members of our research team from Showa Denko work at a laboratory located at this complex. Details are discussed in the article by S. Kitagawa et al. on p. 2747 ff.

      For ethylene/ethane separation by PSA, the adsorption properties of [Cu2(2,3-pyrazinedicarboxylate)2(pyrazine)]n were investigated by both the single and binary gas system, which revealed its ethylene selective nature. Moreover, spectroscopic and computational studies suggested the importance of hydrogen bonds in the selective adsorption of ethylene over ethane.

    2. Bridging Ligands

      Syntheses, Characterization, and Magneto–Structural Analyses in μ1,3-Acetato-Bridged Tetracopper(II) and μ1,3- and μ1,1,3-Acetato-Bridged Pentanickel(II) Clusters (pages 2753–2765)

      Variable-temperature magnetic studies of two structurally characterized pentanuclear nickel(II) complexes and one tetranuclear copper(II) complex synthesized from a series of compartmental ligands reveal both ferromagnetic and antiferromagnetic interactions in the pentanickel complexes and strong antiferromagnetic interactions in tetracopper cluster.

      Five single-side organically decorated Anderson-type molybdoaluminate compounds with R = CH2OH, NH2, CH2CH3, NHCH2COOH and CH2OCH2C(CH2OH)3 have been synthesized through one-step and / or controlled reactions. The strategy utilized represents a common approach for the asymmetric modification of Anderson-type molybdoaluminates.

      A systematic study was conducted on the thermal strength and transparency of four types of silica/silicone composites to determine their effectiveness as filler materials for silicone rubber. Mesoporous silica/silicone composites show the lowest thermal expansion and higher transparency than the other composites, which makes them the most promising filler materials for silicone rubber.

    5. Eu/W Hybrid Catalyst

      Directional Self-Assembly of Exfoliated Layered Europium Hydroxide Nanosheets and Na9EuW10O36·32H2O for Application in Desulfurization (pages 2779–2786)

      Xiaoting Wang, Wei Chen and Yu-Fei Song

      Version of Record online: 7 MAY 2014 | DOI: 10.1002/ejic.201400122

      Thumbnail image of graphical abstract

      The self-assembly of exfoliated layered europium hydroxides (LEuH) and Na9EuW10O36·32H2O (EuW10) led to a new inorganic/inorganic hybrid material, LEuH-Euw10. The use of LEuH-EuW10 in extractive catalytic oxidative desulfurization showed that this catalyst is highly efficient and selective for the deep desulfurization of dibenzothiophene in the presence of H2O2 and [omim]PF6 under mild conditions.

    6. Mesoporous Materials

      Fructose and Urea as Precursors for N-/O-Modified Mesoporous Carbon with Enhanced Sorption Capacity for Heavy Metal Ions (pages 2787–2792)

      Ordered mesoporous carbon with a high heteroatom (N, O) content is prepared by nanocasting from a melt of a eutectic mixture of fructose and urea as cheap and environmentally friendly precursors. The material possesses enhanced pore-wall surface polarity and high sorption capacity for heavy metal ions (Cu2+) from aqueous solution.

      A series of rhodium complexes with a fluorinated β-diketiminato ligand as well as a fluorinated β-ketiminato ligand has been synthesized. Treatment of [Rh{κ2-(N,N)-(C6F5)NC(Me)CHC(Me)N(C6F5)}(CO)(NCMe)] with tertiary silanes HSiR3 (R = Me, Et, iPr, Ph, OMe, OEt) gave the (β-diketiminato)(hydrido)(silyl)rhodium complexes [Rh{κ2-(N,N)-(C6F5)NC(Me)CHC(Me)N(C6F5)}(H)(SiR3)(CO)].

    8. Hydrometallation

      Version of Record online: 8 MAY 2014 | DOI: 10.1002/ejic.201402132

      Thumbnail image of graphical abstract

      Bond activation by intramolecular interactions of alkynyl carbon with highly Lewis acidic aluminium atoms was observed for functionalised alkenyl-alkynylgermanes. Such mixed germanium–aluminum or –gallium compounds were obtained by hydrometallation of dialkynylgermanes and are promising candidates for secondary reactions such as cyclisation or insertion.

    9. Cavity Complexes

      A tris(imidazole) core associated with a resorcinarene provides a biomimetic environment for ZnII complexes. The metal ion is embedded in a five-coordinate environment with two sites open for the coordination of exogenous donors in cis positions relative to each other. Carboxylates, diketonates, and deprotonated amides can selectively bind at the endo and/or exo position.
