      The cover picture shows the potential energy map for CO2 adsorption in a CuII/adeninato/carboxylato metal–biomolecule framework (MBioF) computed by GCMC calculations. The gas adsorption behavior of a family of MBioFs is exhaustively studied on the basis of experimental and simulation data. Moreover, the selectivity towards CO2/H2 and CO/H2 gas mixtures is studied by computing the Henry constants and the binary adsorption isotherms. The results are interpreted by means of potential energy maps, which show how the gas sorption and selectivity features are straightforwardly controlled by modifying the chain length of the carboxylato ligand also shown in the cover picture. Details are discussed in the article by G. Beobide et al. on p. 5921 ff.

    1. Copper Corroles

      Synthesis and Characterization of Copper Undecaarylcorroles and the First Undecaarylcorrole Free Base (pages 5915–5920)

      Di Gao, Gabriel Canard, Michel Giorgi and Teodor Silviu Balaban

      Article first published online: 20 NOV 2012 | DOI: 10.1002/ejic.201201158

      Saddle undecaaryl copper corroles were prepared by a Suzuki cross-coupling procedure. Their saddling dihedral angles strongly depend on the meso substituents, whereas the β-aryl groups induce a redshift of their UV/Vis absorption maxima. The X-ray structure of the demetalated undecaarylcorrole free base shows that full aryl substitution has no impact on the conformation of the corrole.

      Gas Adsorption Properties and Selectivity in CuII/Adeninato/Carboxylato Metal–Biomolecule Frameworks (pages 5921–5933)

      Sonia Pérez-Yáñez, Garikoitz Beobide, Oscar Castillo, Michael Fischer, Frank Hoffmann, Michael Fröba, Javier Cepeda and Antonio Luque

      Article first published online: 19 NOV 2012 | DOI: 10.1002/ejic.201201028

      The gas adsorption capacity of CuII/adeninato/carboxylato MBioFs was analyzed on the basis of experimental and simulation data. The selectivity towards CO2/H2 and CO/H2 gas mixtures was studied by computing the Henry constants and the binary adsorption isotherms. The results show how the sorption features are controlled by modifying the chain length of the carboxylato ligand.

    2. Magnetic Complexes

      Thumbnail image of graphical abstract

      The trinuclear NiII3 and CuII3 triplesalophen complexes exhibit planar molecular structures by the completely sp2 hybridized backbone leading to intermolecular π stacking. The CuII3 complexes exhibit ferromagnetic interactions although a strong heteroradialene contribution is observed.

    3. Heterocyclic Sandwich Complexes

      Biologically Active Trifluoromethyl-Substituted Metallocene Triazoles: Characterization, Electrochemistry, Lipophilicity, and Cytotoxicity (pages 5953–5959)

      Carboxymethyl-dextran can replace the hydrophobic oleylamine ligands on the surfaces of MnO nanoparticles, rendering them highly water-soluble by allowing direct contact with excited water protons. The modification to the dextran converts the nanoparticles into effective T1 MRI contrast agents, as well as promoting strong interactions with macrophages.

      The epoxidation of 1-octene using methyltrioxorhenium (MTO) in the presence of pyridinebis(oxazoline) and related ligands is reported. Although excellent chemoselectivity (>90 %) and good yields were obtained, low enantioselectivity was observed.

      3-(2-Pyridyl)-5-(2-thienyl)pyrazolate anions act as bidentate ligands and form five-membered metallacycles. In addition, these anions can adopt bridging modes as shown in the lithium complex (C grey, Li green, N blue, O red, S yellow; H omitted) or can be deprotonated a second time at the 3-position of the thienyl ring.

    9. Siloxane Lewis Basicity

      On The Lower Lewis Basicity of Siloxanes Compared to Ethers (pages 6002–6010)

      Jack Passmore and J. Mikko Rautiainen

      Article first published online: 15 NOV 2012 | DOI: 10.1002/ejic.201200881

      Thumbnail image of graphical abstract

      Stability differences between disiloxane and diethyl ether metal complexes are attributed to ligand-dependent differences in bonding and polarization. Specifically, repulsive interactions between the positively charged disiloxane Si atoms and metal cations override the greater electrostatic metal affinity of the disiloxane O atom relative to that of OEt2.

      New Pd complexes were synthesized, characterized and used for the microwave-assisted synthesis of Pd nanoparticles (NPs) under various reaction conditions. The growth mechanism of the NPs depended on the halide coligands. The as-synthesized Pd NPs were embedded in wooden matrices, and their catalytic activity was confirmed in organic cross-coupling reactions.
