      Article first published online: 8 MAY 2015 | DOI: 10.1002/ejic.201590053

      The cover picture shows the unexpected rearrangement of the bis(N-heterocyclic carbene)borate chelating ligand induced by the “Kalium” (German for potassium) ion in toluene. This rearrangement affords a unique imidazolyl–NHC–borate potassium salt, which represents a new chelating bis(donor) ligand that is otherwise difficult to synthesize. This ligand allows access to a novel hydridogermyliumylideneborate complex. Details are discussed in the Short Communication by M. Driess et al. on p. 2377 ff. For more on the story behind the cover research, see the Cover Profile.

      Flip the chelate: The unexpected solvent-dependent potassium-induced isomerization of a potassium bis(N-heterocyclic carbene)borate in toluene afforded a unique potassium imidazolyl–NHC–borate isomer, which was successfully utilized for the synthesis and isolation of unprecedented chloro- and hydridogermyliumylideneborate complexes.

    2. Mechanism for Au(III) Catalysis

      Homogeneous Catalysis with AuIII: Insights into the Mechanism of the Alkoxylation of Alkynes (pages 2381–2386)

      Zhi Xiang Wong and Matthias Lein

      Article first published online: 17 APR 2015 | DOI: 10.1002/ejic.201500152

      Thumbnail image of graphical abstract

      A thorough mechanistic study of gold(III)-catalyzed addition of methanol to propyne was carried out by using density functional theory. Each individual process is assisted by explicitly included solvent methanol, which also acts as the nucleophile. Results showed that the double nucleophilic attacks proceed fast over low activation barriers with the last hydrogen migration as the rate-determining step.

      Article first published online: 23 APR 2015 | DOI: 10.1002/ejic.201500127

      Thumbnail image of graphical abstract

      Tin oxometallates incorporating lutidine are synthesized in ethanol/water mixtures containing different anions in various molar ratios. The compounds are liberated from solutions containing several species and show the ability of the tin atom to coordinate to different anions, which are sometimes present in solution at lower concentrations than others.

      Thumbnail image of graphical abstract

      Binary Sb2S3 and Sb2Se3 nanowires as well as ternary Sb2(S,Se)3 nanowires were synthesized by thermal decomposition of four novel single-source precursors of the type (Et2Sb)2E and Et3SbE (E = S, Se) in the presence of suitable capping agents and characterized by XRD, REM, EDX, ED and HRTEM.

    4. N-Heterocyclic Carbenes

      Determining the Ligand Properties of N-Heterocyclic Carbenes from 77Se NMR Parameters (pages 2416–2425)

      Kathrin Verlinden, Hannes Buhl, Walter Frank and Christian Ganter

      Article first published online: 10 APR 2015 | DOI: 10.1002/ejic.201500174

      Thumbnail image of graphical abstract

      The electronic properties of a range of N-heterocyclic carbenes have been evaluated by using the 77Se NMR chemical shifts of NHC–Se adducts, to map the π-acceptor character, and 1JCSe coupling constants, which provide insights into the σ-donor ability of the respective carbene. DFT calculations were conducted to rationalize the data. The NMR-derived parameters have been compared with TEP values.

    5. Mixed-Framework Silicates

      Two Structure Types Based on Si6O15 Rings: Synthesis and Structural and Spectroscopic Characterisation of Cs1.86K1.14DySi6O15 and Cs1.6K1.4SmSi6O15 (pages 2426–2436)

      Maria Wierzbicka-Wieczorek, Martin Göckeritz, Uwe Kolitsch, Christoph Lenz and Gerald Giester

      Article first published online: 16 APR 2015 | DOI: 10.1002/ejic.201500091

      Thumbnail image of graphical abstract

      Two (Cs,K)-REE3+ silicates (REE3+ = Dy or Sm) containing Si6O15 rings represent mixed tetrahedral-octahedral framework structure types. Their crystal structures were characterised by single-crystal X-ray diffraction and photoluminescence spectroscopy. The presence of REE3+ cations in the structures causes emission bands in the visible yellow-to-orange spectral range.

    6. Oxide Copper Complexes

      Investigations Concerning [Cu4OX6L4] Cluster Formation of Copper(II) Chloride with Amine Ligands Related to Benzylamine (pages 2437–2447)

      Sabine Becker, Ulrich Behrens and Siegfried Schindler

      Article first published online: 17 APR 2015 | DOI: 10.1002/ejic.201500115

      Thumbnail image of graphical abstract

      The μ4-oxido motif is well known in copper clusters and often forms spontaneously and unexpectedly. However, little is known about the reaction conditions that generate μ4-oxido clusters. Here, a systematic investigation of μ4-oxido cluster formation is reported. The effects of the ligand environment, central chalcogenide atom, and bridging halide ligands on cluster formation are investigated.

    7. Supercapacitors

      Effects of Co/Ni Ratio on the Supercapacitive Properties of α-Form Hydroxides (pages 2448–2456)

      Lan Liu, Ke-Yuan Ma, Fu Liu, Xiao-Bin Zhang and J. P. Cheng

      Thumbnail image of graphical abstract

      α-Form CoxNi1–x hydroxides have structures similar to that of α-Co(OH)2, with better electrochemical performance than pure α-Co(OH)2. The highest specific capacitance at 1 A g–1 for α-form CoxNi1–x hydroxides is 1696.7 F g–1. An asymmetric supercapacitor using Co0.6Ni0.4 hydroxide and activated carbon as electrode materials has an energy density of 23.5 Wh kg–1 at a power density of 412.5 W kg–1.

      Thibaut Duchanois, Thibaud Etienne, Cristina Cebrián, Li Liu, Antonio Monari, Marc Beley, Xavier Assfeld, Stefan Haacke and Philippe C. Gros

      Article first published online: 14 APR 2015 | DOI: 10.1002/ejic.201500142

      A new iron(II) complex with a record 16 ps triplet metal-to-ligand charge-transfer (3MLCT) state lifetime has been designed and evaluated as a photosensitizer in a laboratory dye-sensitized solar cell (DSSC), which led to measurable photocurrent and power-conversion efficiency. Such an improvement of the photophysical properties of iron-based complexes opens the way to applications that go far beyond energy production.

    11. Boron Nitrides

      Simple Synthesis of Two-Dimensional Micro/Mesoporous Boron Nitride (pages 2478–2485)

      Mahdi Maleki, Ali Beitollahi and Mohammadreza Shokouhimehr

      A facile one-pot synthesis route is presented to prepare micro/mesoporous boron nitride (BN) nanosheets by pyrolysis of cetyl trimethylammonium bromide (CTAB)/ammonia borane (AB) at 1150 °C. Increasing the weight ratio of CTAB/AB changed the morphology of the synthesized materials from densely packed porous structures to micro/mesoporous two-dimensional BN powder.

    12. Hydrogallation

      Heterocyclic Digallanates, Encapsulation of Lithium Cations in Organometallic Cages and C–H Bond Activation (pages 2486–2496)

      Werner Uhl, Anne Hentschel, Dirk Kovert, Jutta Kösters and Marcus Layh

      Article first published online: 23 APR 2015 | DOI: 10.1002/ejic.201500207

      Thumbnail image of graphical abstract

      C–H bond activation and ortho-metallation was achieved by heating novel macrocyclic phenylene centered dilithium di(galliumalkenyl) compounds in solution. The products contained five-membered GaC4 heterocycles. Various Li–π interactions resulted in fascinating molecular structures for the digallanate intermediates and the finally isolated metallacycles.
