      Artem L. Gushchin, Yuliya A. Laricheva, Pavel A. Abramov, Alexander V. Virovets, Cristian Vicent, Maxim N. Sokolov and Rosa Llusar

      Article first published online: 18 JUL 2014 | DOI: 10.1002/ejic.201402343

      Thumbnail image of graphical abstract

      An Mo3S4 cluster coordinated by thiourea ligands is a new precursor in the chemistry of Mo3S4 clusters. Its potential as a convenient starting material has been demonstrated by reactions with 2,2-bipyridine and 1,10-phenanthroline to afford new diimino cluster complexes. The Mo3S4 cluster bearing 1,10-phenanthroline undergoes a reversible two-electron reduction that is phen-centered with strong delocalization on the metal.

    3. Luminescent Platinum Complexes

      Phosphorescent PtII Systems Featuring Both 2,2′-Dipyridylamine and 1,3,5-Triazapentadiene Ligands (pages 4101–4108)

      Article first published online: 18 JUL 2014 | DOI: 10.1002/ejic.201402413

      Thumbnail image of graphical abstract

      It has long been known that Fe0 reagents activate many organosulfur compounds by scission of C–S bonds. Here, we report that S2N2 heterocycles undergo smooth activation by [Fe3(CO)12] to give azamonothiolates, not the well precedented azadithiolates. In these azathiolate complexes, all six CO ligands are diastereotopic.

    5. Metallocenes

      Synthesis and Molecular Structures of Monosubstituted Pentamethylcobaltocenium Cations (pages 4115–4122)

      Anne Wolter-Steingrube, Bernhard E. C. Bugenhagen, Carmen Herrmann and Jürgen Heck

      Article first published online: 22 JUL 2014 | DOI: 10.1002/ejic.201402443

      Thumbnail image of graphical abstract

      From the zwitterion 1, the aminocobaltocenium cation 6+ can be synthesized in five steps. The target compound 6+ demonstrates an electronic structure between that of an amine and that of an iminium cation. It reacts as a weak acid in aqueous solution and can be oxidized to the corresponding nitrocobaltocenium cation 7+ like primary amines.

    6. Reaction Mechanisms

      Kinetics and Mechanism of the Reaction of Hydrogen Sulfide with Diaquacobinamide in Aqueous Solution (pages 4123–4133)

      Denis S. Salnikov, Sergei V. Makarov, Rudi van Eldik, Polina N. Kucherenko and Gerry R. Boss

      Article first published online: 21 JUL 2014 | DOI: 10.1002/ejic.201402082

      Thumbnail image of graphical abstract

      The reduction of diaquacobinamide [(H2O)2Cbi(III)] by hydrogen sulfide proceeds through inner-sphere electron transfer (ISET) in the two complexes with one coordinated HSligand, viz., (HO)(HS)Cbi(III) and (H2O)(HS)Cbi(III), to form the reduced cobinamide complex [(H)S]Cbi(II). ISET does not proceed in the (HS)2Cbi(III) complex.

    7. Environmental Chemistry

      Aerial CO2 Trapped as CO32– Ions in a Dimeric Capsule That Efficiently Extracts Chromate, Sulfate, and Thiosulfate from Water by Anion-Exchange Metathesis (pages 4134–4143)

      Thumbnail image of graphical abstract

      In the solid state, a tripodal urea receptor encapsulates CO32– ions in its dimeric capsular assembly, which is further exploited for the liquid–liquid (L–L) extraction of CrO42–, S2O32–, and SO42– ions from water. Different spectroscopic techniques and X-ray diffraction studies confirm the efficient extraction of these environmentally relevant anions.

    8. Pd–Ni Bimetals

      Compositionally Controlled Self-Assembly of Hierarchical Pd–Ni Bimetallic Chains (pages 4144–4150)

      Peiyu Jin, Xin Liang, Yeheng He, Sijia Liu and Xiaolin Zhu

      Article first published online: 23 JUL 2014 | DOI: 10.1002/ejic.201402173

      Thumbnail image of graphical abstract

      The self-assembly of Pd–Ni bimetals with various compositions was performed by a one-pot reaction. The formation mechanism for these assemblies is proposed, in which the self-assembly behaviours were controlled by the competition between the surfactant interaction and the magnetic dipole interaction. The catalytic performance of these Pd–Ni assemblies is strongly dependent on their compositions.

    9. Cluster Compounds

      The Chemistry of Ni–Sb Carbonyl Clusters – Synthesis and Characterization of the [Ni19Sb4(CO)26]4– Tetraanion and the Viologen Salts of [Ni13Sb2(CO)24]n– Carbonyl Clusters (pages 4151–4158)

      Article first published online: 21 JUL 2014 | DOI: 10.1002/ejic.201402326

      Thumbnail image of graphical abstract

      The reactions of a multicompartmental ligand with rare-earth(III) nitrate salts afford a series of homometallic Ln4 complexes [Ln = Dy, Tb, Gd, and Er] with [2×2] square-grid topology. Magnetic studies reveal the presence of all-antiferromagnetic exchange interactions and ligand-field-induced effects for the Dy, Tb, and Er complexes, whereas an isotropic model suffices for the Gd complex.

    11. Tridentate Ligand Platform

      Neutral and Cationic Alkyl and Amido Group 3 Metal Complexes of Amidine-Amidopyridinate Ligands: Synthesis, Structure, and Polymerization Catalytic Activity (pages 4168–4178)

      Thumbnail image of graphical abstract

      The structure of a [Pc–Tb–Pc*] SMM was determined. A single-crystal X-ray diffraction analysis revealed an effective intermolecular π–π interaction leading to the formation of π dimers, which are stacked with neighboring dimers in parallel columns with an axis tilted by 30° with respect to the C4 axis of individual molecules. Isostructural Dy and Ho analogues were synthesized and characterized.

    13. Photoluminescence
