      The cover picture shows the blue northern French sky and the central [Co(H2O)(NC)5]2– unit of the fascinating Prussian Blue analogue. This material undergoes spin-transition and electron transfer from an FeII to a CoIII site, upon external stimulation, i.e. visible light. Overall, it passes from a diamagnetic to a ferrimagnetic state. The intrinsic {Fe(CN)6}4– vacancy leads to a replacement of an apical cyano ligand by an aqua ligand. Like a hammer hits a nail, this vacancy seems to provoke a deformation of the CoIII ion out of the equatorial plane. Our quantum chemical investigation attributes thus an important role to the apical vacancy. Details are discussed in the article by T. Krah, N. Ben Amor et al. on p. 5777 ff.

      Chlorogermylene and (diazomethyl)germylene tungsten pentacarbonyl complexes were synthesized and fully characterized. (Diazomethyl)germylene is a precursor of germa-alkyne, and its photolysis when complexed to tungsten was studied. This preliminary work has led to the development of an original strategy in order to access new heteronuclear alkyne complexes of d-block elements.

      On the route towards a better understanding of the photomagnetic properties of the CoFe Prussian Blue analogue, the impact of vacancy-induced deformations and alkali cations on the electronic structure of the embedded [Co(NC)5(H2O)]2– cluster were investigated by ab initio quantum chemistry calculations.

    2. Crystal Engineering in MOFs

      Facile Synthesis of MIL-68(In) Films with Controllable Morphology (page 0)

      Jia Liu, Feng Zhang, Xiaoqin Zou, Shuyuan Zhou, Lina Li, Fuxing Sun and Shilun Qiu

      Version of Record online: 19 OCT 2012 | DOI: 10.1002/ejic.201200642

      Thumbnail image of graphical abstract

      MIL-68(In) films with varied morphologies have been fabricated facilely by a secondary growth approach. The factors influencing the morphologies of the films were studied in detail and a possible mechanism for crystal growth in the films was proposed. This facile approach provides a general route for the preparation of metal–organic framework films for innovative materials.

      A simple tripodal thiourea receptor can extract fluoride as well as sulfate from aqueous media by a liquid–liquid extraction technique using an anion-exchange strategy.

    4. Metal–Organic Frameworks

      Structure and Magnetic Behavior of CuII MOFs Supported by 1,2,4-Triazolyl-Bifunctionalized Adamantane Scaffold (pages 5802–5813)

      Ganna A. Senchyk, Andrey B. Lysenko, Eduard B. Rusanov, Alexander N. Chernega, Julia Jezierska, Konstantin V. Domasevitch and Andrew Ozarowski

      Version of Record online: 15 OCT 2012 | DOI: 10.1002/ejic.201200873

      Thumbnail image of graphical abstract

      Owing to their adamantane scaffold, the linear 1,2,4-triazolyl (tr) supported magnetic clusters [Cu32-tr)6] are set up together at average distances of 11.2 and 15.0–15.6 Å to form square-grid-like networks. The integrated [Cu32-tr)6] units and [Cu(μ2-tr)22-SO4)] chains are the key structural features of the 2D coordination motifs.

    5. Molecular Magnets

      Magnetostructural Studies on Tetranuclear Manganese [MnIII2MnII2] Complexes of 9-Hydroxyphenalenone with Weak π···π Interactions (pages 5814–5824)

      Suman Kr Dey, Andreas Honecker, Partha Mitra, Swadhin K. Mandal and Arindam Mukherjee

      Version of Record online: 8 OCT 2012 | DOI: 10.1002/ejic.201200800

      Thumbnail image of graphical abstract

      Two tetranuclear mixed-valent MnII/III complexes resemble a “rhomboidal”/“butterfly” motif except that the MnIII ions are at the “wing-tip” and MnII ions in the “body” positions. The magnetic data fit well with two different coupling constants, and it appears that the exchange coupling constants correlate with the solid angle formed by the μ3-O(alk)oxo bonded to the MnII/III ions.

    6. Magnetic Properties

      Magnetic Structures of HoCoO3 and TbCoO3 (pages 5825–5830)

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/ejic.201200811

      Thumbnail image of graphical abstract

      HoCoO3 and TbCoO3 present an antiferromagnetic ordering below TN = 3 and 3.6 K, respectively. In both cases, only the rare earth R3+ ion is involved in the magnetic ordering. The Co3+ ions exhibit a low-spin electronic configuration t2g6eg0 with S = 0.

    7. Nanoribbons

      Synthesis of Mesoporous MoO3 Nanoribbons through a Multi-molybdate Coordination-Polymer-Precursor Route (pages 5831–5836)

      Longqiang Wang, Peng Gao, Guoli Zhang, Guorui Chen, Yujin Chen, Ying Wang and Di Bao

      Version of Record online: 5 OCT 2012 | DOI: 10.1002/ejic.201200519

      Thumbnail image of graphical abstract

      A multi-molybdate coordination-polymer-precursor ({Mo36} ions) route was developed to synthesize mesoporous MoO3 nanoribbons. By controlling the experimental conditions, the {Mo36} ions underwent directed assembly and dehydration to form 1D mesoporous MoO3 nanoribbons. The nanoribbons exhibited high selectivity, high sensor response, and low working temperature to H2S gas.

      The spin transition and thermal hysteresis of gold-coated particles of the spin-crossover [Fe(Htrz)2(trz)] (BF4)·H2O polymeric complex were successfully monitored by means of resonance Raman spectroscopy using the 325 nm excitation line that is in pre-resonance with the MLCT electronic absorption band of the low-spin state of the complex.

      A new family of CuI complexes exhibit versatile and efficient catalytic activity in Huisgen cycloadditions of azides and 1-iodoalkynes in aqueous media under mild conditions; these are the first well-defined CuI catalysts found to be active in a three-component reaction with 1-iodoalkynes in aerobic aqueous conditions.

    11. Titanium Dioxide Nanoparticles

      Facile Synthesis and Active Photocatalysis of Mesoporous and Microporous TiO2 Nanoparticles (pages 5864–5871)

      Gai Miao, Lifang Chen and Zhiwen Qi

      Version of Record online: 16 OCT 2012 | DOI: 10.1002/ejic.201200833

      Thumbnail image of graphical abstract

      Crystallised meso- and microporous high-surface anatase TiO2 were obtained by combining the sol–gel method with solvothermal treatment. The TiO2 displayed superior high photocatalytic activity for the degradation of methyl blue (MB) and methyl orange (MO) under near-UV irradiation, which may be mainly ascribed to the fully crystallised uniform anatase TiO2 nanoparticles with exposed {100} facets.

    12. Bis(NHC)–Palladium Complexes

      Palladium(II) Complexes with Chelating Biscarbene Ligands in the Catalytic Suzuki–Miyaura Cross-Coupling Reaction (pages 5872–5880)

      Version of Record online: 17 OCT 2012 | DOI: 10.1002/ejic.201200940

      Thumbnail image of graphical abstract

      The catalytic activity of palladium(II) complexes with chelating bis(N-heterocyclic carbene) [bis(NHC)] ligands was tested in the Suzuki–Miyaura cross-coupling reaction. After an investigation of electronic as well as steric effects of substituents on the aromatic rings of the ligand, the most active complex was used to couple different aryl bromides under mild conditions in excellent yields.

    13. Alkynes and Zeise's Dimer

      Dinuclear Olefin and Alkyne Complexes of Platinum(II) (pages 5881–5895)

      Anja König, Martin Bette, Clemens Bruhn and Dirk Steinborn

      Version of Record online: 17 OCT 2012 | DOI: 10.1002/ejic.201200744

      Thumbnail image of graphical abstract

      Zeise's dimer [{PtCl2(H2C=CH2)}2] and related complexes reacted with internal alkynes RC≡CtBu (R = Me, tBu) to yield the alkyne complexes [{PtCl2(RC≡CtBu)}2] and/or mononuclear mixed ethene/alkyne complexes cis-[PtCl2(H2C=CH2)(RC≡CtBu)] (R = Me, tBu). With alkynes RC≡CR′ bearing less bulky substituents (R, R′ = Me, Et, nPr, Ph), (cyclobutadiene)platinum(II) complexes [PtCl2(C4R2R′2)] were obtained.
