      The cover picture shows the blue solution of bis(N-hexadecylpyridinium) tetrakis(dicyanamido)cobaltate in acetone, from which it is finally isolated by evaporation of the solvent as the purple powder (also depicted). In the foreground, a three-dimensional model of the dicyanamide anion is shown, which represents the crucial chemical building block of our system. The anion can coordinate to transition metals, such as Ni2+ and Co2+, while the depicted pyridinium or imidazolium ions are used as countercations. The resulting (dicyanamido)metallate salts can be used as highly versatile precursors for interesting materials, of which some electron micrographs are shown exemplarily on the right side of the picture. Details are discussed in the article by J. P. Paraknowitsch et al. on p. 4105 ff.

    1. Mesoporous Composite Materials

      One-Pot Synthesis of Metal-Doped Mesoporous Materials from (Dicyanamido)metallate Precursors (pages 4105–4116)

      Jens Peter Paraknowitsch, Oyunbileg Sukhbat, Yuanjian Zhang and Arne Thomas

      Version of Record online: 8 AUG 2012 | DOI: 10.1002/ejic.201200680

      (Dicyanamido)metallates are shown to be a novel and highly promising class of precursors for the synthesis of metal-doped materials. With their simultaneous action as structure-directing agents, N-doped carbon precursors and metal dopants, facile one-pot synthetic approaches for multiply functionalised composite materials become accessible.

    2. Disordered Crystals

      Pseudo-Polymorphism in a Conformationally Rigid Copper Helicate – Structural Studies of a Shape-Awkward System (pages 4117–4130)

      Marta Martinez Belmonte and Daniel J. Price

      Version of Record online: 8 AUG 2012 | DOI: 10.1002/ejic.201200676

      Thumbnail image of graphical abstract

      The potassium salts of a pseudospherical anionic copper helicate crystallise in a large number of different arrangements. These phases are typified by structural order of the anion and by much disorder in the position of the cations.

    3. High-Spin Mn Clusters

      Adsorption of [Mn19] Aggregates with S = 83/2 onto HOPG Surfaces (pages 4131–4140)

      Ayuk M. Ako, Mohammad Sahabul Alam, Samir Mameri, Yanhua Lan, Marcel Hibert, Michael Stocker, Paul Müller, Christopher E. Anson and Annie K. Powell

      Version of Record online: 3 AUG 2012 | DOI: 10.1002/ejic.201200420

      Thumbnail image of graphical abstract

      The adsorption of high-spin Mn19 clusters onto highly oriented pyrolytic graphite (HOPG) substrates was studied by scanning tunneling microscopy (STM) and current imaging tunneling spectroscopy (CITS). The clusters orient with their threefold axes parallel or normal to the surface, forming either 1D chains or small groups; the observed morphology is sensitive to the ligand substituent.

    4. Polar Intermetallics

      Several New Phases in RE–Mg–Ge Systems (RE = Rare Earth Metal) – Syntheses, Structures, and Chemical Bonding (pages 4141–4148)

      Nian-Tzu Suen and Svilen Bobev

      Version of Record online: 7 AUG 2012 | DOI: 10.1002/ejic.201200619

      Thumbnail image of graphical abstract

      The focus of this paper is on the crystal and electronic structures of eight new compounds in the ternary RE–Mg–Ge systems (RE = Ce, Pr, Nd, Sm). A common building block of all the structures is the MgGe4 tetrahedron, which shares edges or corners to form polyanionic frameworks. This work has shown a very rich, but poorly mapped phase-space, with potentially many more compounds awaiting discovery.

    5. Dicopper Complexes

      Synthesis and Characterization of a (μ-η22-Peroxido)dicopper(II) Complex with N,N′,N″-Triisopropyl-cis,cis-1,3,5-triaminocyclohexane (R3TACH, R = iPr): Selective Preparation of (μ-η22-Peroxido)dicopper(II) and Bis(μ-oxido)dicopper(III) Species Regulated by Substituent Groups (pages 4149–4158)

      Jun Matsumoto, Yuji Kajita and Hideki Masuda

      Version of Record online: 6 AUG 2012 | DOI: 10.1002/ejic.201200228

      Thumbnail image of graphical abstract

      The selective preparation of (μ-η22-peroxido)dicopper(II) and bis(μ-oxido)dicopper(III) species is regulated by the substituent groups of triaminocyclohexane derivative ligands. Their structural and spectroscopic features and reactivity are discussed.

    6. Bioinorganic Chemistry

      Synthesis of [MoS4]2––M (M = Cu and Cd) Clusters: Potential NMR Spectroscopic Structural Probes for the Orange Protein (pages 4159–4166)

      Biplab K. Maiti, Teresa Avilés, Manolis Matzapetakis, Isabel Moura, Sofia R. Pauleta and José J. G. Moura

      Version of Record online: 3 AUG 2012 | DOI: 10.1002/ejic.201200551

      Thumbnail image of graphical abstract

      Structural Probes: The orange protein (ORP) contains an unusual cofactor, [S4MoCuMoS4]3–, that is EPR-silent and lacking atoms suitable for NMR spectroscopic analysis. Therefore, NMR-active structural model compounds that can be used to probe the cluster-binding site in the ORP were synthesized.

      CpCo(1,3-C3B2Me5H) (1) reacts with CpTl to give CpCo(1,3-C3B2Me5)Tl (2). The structures of 1 and 2 were determined by X-ray diffraction. The “extra” hydrogen atom in 1 occupies a C–H···B bridging position.

    9. Mesoporous Silica

      Preparation of High-Quality MCM-48 Mesoporous Silica and the Mode of Action of the Template (pages 4183–4189)

      Version of Record online: 2 AUG 2012 | DOI: 10.1002/ejic.201200316

      Thumbnail image of graphical abstract

      Ultrastable MCM-48 silica with Ia3d symmetry was directly synthesized by using the surfactant cetyltrimethylammonium tosylate (CTATos) as template. The obtained MCM-48 silica has a highly ordered structure and large surface area (ca. 1281 m2/g) and pore volume (ca. 1.07 cm3/g).

    10. NU-10 Zeolite Desilication

      Towards a Deep Desilication/Dealumination of NU-10 Zeolite: Shape-Selectivity Regulation (pages 4190–4199)

      Clara Sá Couto, Patrícia Matias, Edgar T. Santos, Auguste Fernandes, Inês Graça, José M. Lopes and Maria F. Ribeiro

      Version of Record online: 31 JUL 2012 | DOI: 10.1002/ejic.201200386

      Thumbnail image of graphical abstract

      A wide range of desilication levels, as well as of mesopore volume generation, was induced by alkaline treatment of NU-10 zeolite, which presents a 1D microporous network of intermediate pore sizes. Remarkable improvements in the activity per acid site (TOF) for o-xylene transformation and a controlled manipulation of the shape selectivity (expressed in the p/m-xylenes ratio) were achieved.

    11. Calcium Aluminate Adducts

      Complex Formation of Calcium Bis(tetraethylaluminate) with N-Donor Ligands (pages 4200–4209)

      Matthias Hülsmann, Beate Neumann, Hans-Georg Stammler and Norbert W. Mitzel

      Version of Record online: 31 JUL 2012 | DOI: 10.1002/ejic.201200453

      Thumbnail image of graphical abstract

      Calcium bis(tetraethylaluminate) was treated with two- and three-dentate N-donor ligands to give adducts with different hapticity of the aluminate ligands in the solid state and highly dynamic intra- and intermolecular behaviour in solution.

    12. Cobalt Clusters

      Calixarene-Supported Polynuclear Cobalt(II) Cluster Complexes Tuned by Substitution Groups of the Second Bridging Ligands (pages 4210–4217)

      Cai-Ming Liu, De-Qing Zhang, Xiang Hao and Dao-Ben Zhu

      Version of Record online: 8 AUG 2012 | DOI: 10.1002/ejic.201200682

      Thumbnail image of graphical abstract

      An efficient approach is developed for modifying the nanoscale calixarene-supported polynuclear cobalt(II) complexes with a closed wheel-like or an open rod-like structure, depending on the 5-substituent groups of the 1H-tetrazole bridging ligands. Both complexes are constructed from two different types of polymetallic cluster subunits and show antiferromagnetic interactions.

    13. Catalytic Nitrile Hydration

      Arene-Ruthenium(II) and Bis(allyl)-Ruthenium(IV) Complexes Containing 2-(Diphenylphosphanyl)pyridine Ligands: Potential Catalysts for Nitrile Hydration Reactions? (pages 4218–4230)

      Rocío García-Álvarez, Sergio E. García-Garrido, Josefina Díez, Pascale Crochet and Victorio Cadierno

      Version of Record online: 3 AUG 2012 | DOI: 10.1002/ejic.201200592

      Thumbnail image of graphical abstract

      In the search for cooperative effects of ligands, several arene-ruthenium(II) andbis(allyl)-ruthenium(IV) complexes with 2-(diphenylphosphanyl)pyridines have been synthesized and studied as potential catalysts for the selective hydration of nitriles to amides. A bifunctional catalysis mechanism was discarded.
