      Factors That Determine the Mechanism of NO Activation by Metal Complexes of Biological and Environmental Relevance (Eur. J. Inorg. Chem. 4/2013)

      Alicja Franke and Rudi van Eldik

      Article first published online: 23 JAN 2013 | DOI: 10.1002/ejic.201390016

      The cover picture shows the various aspects that influence the mechanism of interaction of NO with transition-metal complexes of biological and environmental relevance in solution. The underlying reaction mechanism is, in many cases, an unsolved puzzle, such that the key to a specific aspect can reveal details not known or not understood before. In this way, different aspects such as the nature of the metal complex, solvent and experimental conditions (temperature and pressure) can play a key role. Details are presented in the Microreview by A. Franke and R. van Eldik on p. 460 ff.

    1. NO Activation by Metal Complexes

      Factors That Determine the Mechanism of NO Activation by Metal Complexes of Biological and Environmental Relevance (pages 460–480)

      Alicja Franke and Rudi van Eldik

      Article first published online: 19 DEC 2012 | DOI: 10.1002/ejic.201201111

      Thumbnail image of graphical abstract

      The chemical diversity of the systems surveyed in this review gave the opportunity to evaluate and analyze aspects that concern the complexity of NO activation mechanisms. They involve the effect of the chemical properties of the reaction medium, electronic nature of the leaving ligand, environment of the coligand, and steric hindrance around the metal center, on NO activation by Fe and Ru complexes.

      Dmitry S. Perekalin, Eduard E. Karslyan, Evgeniya A. Trifonova, Andrew I. Konovalov, Natalia L. Loskutova, Yulia V. Nelyubina and Alexander R. Kudinov

      Article first published online: 4 DEC 2012 | DOI: 10.1002/ejic.201201112

      Thumbnail image of graphical abstract

      The readily available (naphthalene)ruthenium complex 1 was shown to be a convenient precursor for various [CpRuL2X] complexes and an efficient catalyst for the cyclotrimerization of 1,6-diynes with assorted alkynes.

    2. Photosensitizers

      Click Chemistry as a Convenient Tool for the Incorporation of a Ruthenium Chromophore and a Nickel–Salen Monomer into a Visible-Light-Active Assembly (pages 494–499)

      Christian Herrero, Luke Batchelor, Aurélie Baron, Sanae El Ghachtouli, Sujitraj Sheth, Régis Guillot, Boris Vauzeilles, Marie Sircoglou, Talal Mallah, Winfried Leibl and Ally Aukauloo

      Article first published online: 4 DEC 2012 | DOI: 10.1002/ejic.201201161

      Thumbnail image of graphical abstract

      Click chemistry led to the rapid synthesis of a photosensitiser–metal complex. Under visible light excitation, and in the presence of an electron acceptor, intramolecular photoinduced electron transfer was triggered to oxidise the nickel(II) ion lodged in the salen moiety.

    3. Supported Catalysts

      A Single Source Precursor Route to Group 13 Homo- and Heterometallic Oxides as Highly Active Supports for Gold-Catalyzed Aerobic Epoxidation of trans-Stilbene (pages 500–510)

      Shashank Mishra, Violaine Mendez, Erwann Jeanneau, Valérie Caps and Stéphane Daniele

      Article first published online: 14 DEC 2012 | DOI: 10.1002/ejic.201201191

      Thumbnail image of graphical abstract

      Highly efficient catalysts for aerobic oxidation reactions were obtained by depositing gold nanoparticles on group 13 mono- or mixed metal oxides prepared from the hydrolysis of well-characterized homo- and heterometallic N-methyldiethanolaminate derivatives.

    4. Porous Spin Crossover

      Effect of Spin-Crossover-Induced Pore Contraction on CO2–Host Interactions in the Porous Coordination Polymers [Fe(pyrazine)M(CN)4] (M = Ni, Pt) (pages 511–519)

      Jeffrey T. Culp, De-Li Chen, Jinchen Liu, Danielle Chirdon, Kristi Kauffman, Angela Goodman and J. Karl Johnson

      Article first published online: 5 DEC 2012 | DOI: 10.1002/ejic.201201265

      Thumbnail image of graphical abstract

      Modeling results confirm that the pore widths of the pillared Hofmann compounds [Fe(pyrazine)M(CN)4] are a good fit for adsorbed CO2, which spans the perpendicular distance between pyrazine pillar ligands through a four-fold hydrogen-bonding arrangement. Analysis shows how pore contraction resulting from a shortening of the Fe–N bonds during spin crossover enhances these H···O interactions.

    5. Polynuclear Cluster Topology

      A Database of Topological Representations of Polynuclear Nickel Compounds (pages 520–526)

      Paul Wix, George E. Kostakis, Vladislav A. Blatov, Davide M. Proserpio, Spyros P. Perlepes and Annie K. Powell

      Article first published online: 17 DEC 2012 | DOI: 10.1002/ejic.201201348

      Thumbnail image of graphical abstract

      All coordination clusters containing five or more Ni centers were analyzed by a recently developed automatic method that identified 318 compounds adopting 126 topologically different motifs. A database was created in which all of the Ni compounds can be searched by cluster topological symbol and nuclearity, compound name, year, and Refcode, as well as by their representation in the Protein Data Bank.

    6. Trinuclear Assemblies

      Pseudohalide-Controlled Assemblies of Copper–Schiff Base Complexes with an Encapsulated Sodium Ion: Synthesis, Crystal Structure, and Computational Studies (pages 527–536)

      Monami Maiti, Dipali Sadhukhan, Santarupa Thakurta, Shubhatam Sen, Ennio Zangrando, Ray J. Butcher, Ramesh C. Deka and Samiran Mitra

      Article first published online: 4 DEC 2012 | DOI: 10.1002/ejic.201200916

      Thumbnail image of graphical abstract

      Three new hetero trinuclear LCu–Na–CuL cationic-unit-based complexes 13 with N2O4 donor Schiff bases have been synthesized and characterized by spectroscopic techniques as well as single-crystal X-ray diffraction analysis. The CuL units interact to encapsulate the sodium ion in a propeller-like fashion in 1 and to sandwich the sodium in 2 and 3.

    7. Polymerization Catalysis

      An Efficient Titanium Amidinate Catalyzed Version of Ziegler's “Aufbaureaktion” (pages 537–544)

      Johannes Obenauf, Winfried P. Kretschmer, Tobias Bauer and Rhett Kempe

      Article first published online: 7 DEC 2012 | DOI: 10.1002/ejic.201201194

      Thumbnail image of graphical abstract

      New ammonium titanates undergo polyethylenyl chain transfer polymerization to triethylaluminium after activation with d-MAO (“dry methylaluminoxane”). Polymerization activities of up to 1000 kgPE molcat–1 h–1 bar–1 in the presence of 1000 equiv. of triethylaluminium were observed. Linear aluminium-terminated polyethylene is found. This polymerization process can be viewed as an efficient version of Ziegler's “Aufbaureaktion”.

      Reaction of deprotonated RC(S)NHP(S)(OiPr)2 [R = EtNH (HLI), iPrNH (HLII), Et2N (HLIII), 2,5-Me2C6H3NH (HLIV), 4-Me2NC6H4NH (HLV)] with NiII leads to [NiLI–V2]. The metal atom is found to be in a square-planar trans-N2S2 ([NiLII,IV2]) or in a square-planar trans-S2S′2 ([NiLI,III2]) environment. Reaction of LV with NiII leads to [Ni(L-1,3-N,S)2] or [Ni(L-1,5-S,S′)2]·(CH3)2C=O crystals.

      Thumbnail image of graphical abstract

      Hydro(solvo)thermal reactions of CuX2 or CuI with tetrazolato ligands in the presence of HX generate tetrazolate-based coordination polymers with cationic copper(I) halide motifs, including eight-connected square-planar layered structures with butterfly-like [Cu4Br2]2+ units, a ten-connected ZrIn2 topological framework with [Cu3Cl]2+ units, and a 3D pillar layered framework with [Cu2Br]nn+ layers.
