    1. Structure–Photoluminescence Quenching

      Structure–Photoluminescence Quenching Relationships of Iridium(III)–Tris(phenylpyridine) Complexes (pages 1025–1037)

      Albert Ruggi, Matteo Mauro, Federico Polo, David N. Reinhoudt, Luisa De Cola and Aldrik H. Velders

      Version of Record online: 11 JAN 2012 | DOI: 10.1002/ejic.201101315

      Thumbnail image of graphical abstract

      A family of four tris(2-phenylpyridine)-based IrIII complexes with hemicaged or open (without capping unit but with similar functional groups on the ligand) structure are reported. Within the context of the parent tris(2-phenylpyridine) and the full-cage iridium(III) complexes, structure–photoluminescence quenching relationships (SPQR) of the four complexes have been investigated.

    2. Porphyrin Chemistry

      A Systematic Study of Electrochemical and Spectral Properties for the Electronic Interactions in Porphyrin–Triphenylamine Conjugates (pages 1038–1047)

      Chih-Yen Huang, Chao-Yen Hsu, Luo-Yi Yang, Chia-Jung Lee, Te-Fang Yang, Chia-Chan Hsu, Chung-Hsiu Ke and Yuhlong Oliver Su

      Version of Record online: 30 JAN 2012 | DOI: 10.1002/ejic.201101033

      Thumbnail image of graphical abstract

      A series of porphyrin–triphenylamine (TPA) conjugates have been characterized by spectral and electrochemical methods. Due to the antenna effect of these conjugates, the fluorescence intensity was enhanced. The oscillator strength increases as the number of TPA substituents increases for the charge-transfer band in the near-IR region upon porphyrin-ring oxidation.

    3. Metal–Organic Macrocycles

      Syntheses and Structural Study of Novel Tetranuclear Bis(phenoxido)-Bridged CuII Metal–Organic Macrocycles (pages 1048–1053)

      Antti Riisiö, Mikko M. Hänninen and Reijo Sillanpää

      Version of Record online: 27 JAN 2012 | DOI: 10.1002/ejic.201101103

      Thumbnail image of graphical abstract

      The geometrical parameters and magnetic properties of structurally interesting metal–organic macrocycles {[Cu4(L)2]·xS and [Cu4(L)2(H2O)2]·xS} can be varied drastically by changing the crystallization solvent. Six novel structures are reported along with their calculated magnetic coupling constants.

    4. Gas-Phase Chemistry

      Activation of Gas-Phase Uranyl Diacetone Alcohol Coordination Complexes by Spectator Ligand Addition (pages 1054–1060)

      Daniel Rios and John K. Gibson

      Version of Record online: 3 FEB 2012 | DOI: 10.1002/ejic.201200024

      Thumbnail image of graphical abstract

      Gas-phase addition of a basic ligand to dipositive uranyl coordination complexes comprising diacetone alcohol results in dehydration to produce mesityl oxide. A novel attribute of this process is that a ligandexothermically associates to a coordination complex, providing excitation to induce chemistry in other ligands; the added “spectator ligand” remains intact.

    5. Silver Sulfonate Complexes

      Synthesis and Structure of Silver Amino-Arenesulfonates (pages 1061–1071)

      Madleen Busse, Philip C. Andrews and Peter C. Junk

      Version of Record online: 31 JAN 2012 | DOI: 10.1002/ejic.201101119

      Thumbnail image of graphical abstract

      Silver(I) amino-arenesulfonate complexes of the formula [Ag(O3SR)] were formed through treatment of a variety of amino-arenesulfonic acids with Ag2O in water. Crystal structure analysis on four complexes indicate 1D chains and 2D and 3D networks depending on the nature and position of the amino (or N) substituent. FTIR and MS studies suggest all the complexes are polymeric in the solid state.

    6. CO-Releasing Molecules

      Derivatives of Photosensitive CORM-S1 – CO Complexes of Iron and Ruthenium with the (OC)2M(S–C–C–NH2)2 Fragment (pages 1072–1078)

      Vaneza P. Lorett Velásquez, Taghreed M. A. Jazzazi, Astrid Malassa, Helmar Görls, Guido Gessner, Stefan H. Heinemann and Matthias Westerhausen

      Version of Record online: 31 JAN 2012 | DOI: 10.1002/ejic.201101230

      Thumbnail image of graphical abstract

      CO-releasing molecules are important as therapeutic agents and pharmaceuticals. Light-triggered CO release can be achieved for iron-containing carbonyl complexes stabilized with aminoethylthiolate or related bases, whereas homologous ruthenium derivatives are stable when exposed to visible light. These complexes capture neutral Lewis bases through N–H···O hydrogen bridges.

    7. Vanadium Coordination Chemistry

      Coordinating Properties of Pyrone and Pyridinone Derivatives, Tropolone and Catechol toward the VO2+ Ion: An Experimental and Computational Approach (pages 1079–1092)

      Daniele Sanna, Péter Buglyó, Linda Bíró, Giovanni Micera and Eugenio Garribba

      Version of Record online: 3 FEB 2012 | DOI: 10.1002/ejic.201101249

      Thumbnail image of graphical abstract

      The chelating and spectroscopic properties of pyrone and pyridinone derivatives, tropolone and catechol (which form very effective antidiabetic compounds) towards the VO2+ ion are explained in terms of aromaticity of the fully deprotonated form of the ligands, and of total electric charge on the oxygen donors.

    8. Multidentate Enaminone Ligands

      Bidentate and Tetradentate β-Aminovinyl Trifluoromethylated Ketones and Their Copper(II) Complexes: Synthesis, Characterization and Redox Chemistry (pages 1093–1103)

      Nicolas Chopin, Maurice Médebielle and Guillaume Pilet

      Version of Record online: 27 JAN 2012 | DOI: 10.1002/ejic.201101385

      Thumbnail image of graphical abstract

      Structural variation of the trifluoromethylated enaminone building block gave rise to new bidentate and tetradentate ligands that bear redox-active units (anthracene, azobenzene and tetrathiafulvalene). Their coordination chemistry with copper(II), structural characterization, redox chemistry and UV/Vis properties of the ligands and complexes have been investigated.

    9. Iron Carbonyl Thiocarbonyls

      New Structural Features in Tetranuclear Iron Carbonyl Thiocarbonyls: Exotriangular Iron Atoms and Six-Electron-Donating Thiocarbonyl Groups Bridging Four Iron Atoms (pages 1104–1113)

      Zhong Zhang, Qian-shu Li, R. Bruce King and Henry F. Schaefer III

      Version of Record online: 17 JAN 2012 | DOI: 10.1002/ejic.201100942

      Thumbnail image of graphical abstract

      The lowest energy Fe4(CS)4(CO)12 structures have a central Fe3 triangle with an exotriangular iron atom joined to the Fe3 triangle by a four-electron donor “end-on” CS bridge. An Fe4 rhombus bridged by a six-electron donor η24-CS group is found in the lowest energy structures of Fe4(CS)4(CO)10 and Fe4(CS)4(CO)9 and makes Fe4(CS)4(CO)10 viable enough to be a promising synthetic objective.

    10. Metal–Metal Communication

      Ferrocenyl Maleimides – Synthesis, (Spectro-)Electrochemistry, and Solvatochromism (pages 1114–1121)

      Alexander Hildebrandt, Steve W. Lehrich, Dieter Schaarschmidt, Romy Jaeschke, Katja Schreiter, Stefan Spange and Heinrich Lang

      Version of Record online: 31 JAN 2012 | DOI: 10.1002/ejic.201101191

      Thumbnail image of graphical abstract

      Ferrocenylmaleimides are accessible by bromine shift and oxidation with subsequent Negishi ferrocenylation of dibromo-N-methylpyrrole. Electrochemical and spectroelectrochemical studies highlight their redox and electron-transfer properties. Additionally, the ferrocenylmaleimides show a significant solvatochromic behavior.

    11. Coordination Polymers

      Expected and Unconventional Ag+ Binding Modes in Heteronuclear Pt,Ag Coordination Polymers Derived from trans-[Pt(methylamine)2(pyrazole)2]2+ (pages 1122–1129)

      Pilar Brandi-Blanco, Pablo J. Sanz Miguel and Bernhard Lippert

      Version of Record online: 30 JAN 2012 | DOI: 10.1002/ejic.201101197

      Thumbnail image of graphical abstract

      Not (only) the available second-ring N atom of pyrazole and pyrazolate ligands in complexes of PtII appears to be the preferred Ag+ binding site in moderately acidic aqueous solution, but rather the C4 atom and/or the C4,C5 double bond.

    12. Multinuclear Zinc Complexes

      Di-, Tetra-, Penta- and Polynuclear Zinc Complexes Supported by a Flexible Tetradentate Schiff Base Ligand (pages 1130–1138)

      David J. D. Wilson, Christine M. Beavers and Anne F. Richards

      Version of Record online: 24 JAN 2012 | DOI: 10.1002/ejic.201101202

      Thumbnail image of graphical abstract

      The coordination preferences of the tetradentate Schiff base N,N′-ethylenebis(4-iminopentan-2-one), H2L, with Et2Zn under various stoichiometries were investigatedand the reactivity of the resultant products was explored. These reactions afforded a series of di-, tetra- and polynuclear zinc complexes.

    13. Niobocene for ROP Catalysis

      Molecular Structure of a Hydridoniobocene Complex [Nb(η5-C5H4SiMe3)2(H)3] and Its Use as Catalyst for the Ring-Opening Polymerization of Cyclic Esters (pages 1139–1144)

      Carlos Alonso-Moreno, Antonio Antiñolo, Joaquín C. García-Martínez, Santiago García-Yuste, Isabel López-Solera, Antonio Otero, Juan C. Pérez-Flores and Maria T. Tercero-Morales

      Version of Record online: 3 FEB 2012 | DOI: 10.1002/ejic.201101263

      Thumbnail image of graphical abstract

      The structure of [Nb(η5-C5H4SiMe3)2(H)3] (1) justifies its classification as a “nonclassical” transition metal hydride. Complex 1 is an initiator for the ROP of lactones. A mechanism consisting of an interaction between the lactone carbonyl group and the metal, insertion of the lactone into the Nb–H bond, and the generation of a metal alkoxide–aldehyde propagating species has been proposed.
